Re: Failing to archive many messages

2024-05-18 Thread Francis Augusto Medeiros-Logeay via dovecot

Today I realized that it was indeed the sa-learn that is slowing down my 
Archiving.

I added an «&» on the end of the line that calls the sa-learn (called by the 
report-ham.sieve script):

exec /usr/bin/sa-learn -u ${1} --ham  &

Does anyone thing this is a bad idea? I noticed that archiving got way faster 
this way…

Best,

Francis

Sieve extprograms pipe :try cancels implicit keep

2024-05-17 Thread Sebastiaan Hoogeveen via dovecot

Hi,

When using the :try tag on the pipe command in the sieve_extprograms plugin 
Sieve’s implicit keep is cancelled if the executed command fails. The 
specification on 
https://raw.githubusercontent.com/dovecot/pigeonhole/master/doc/rfc/spec-bosch-sieve-extprograms.txt
 states:

“When the ":try" tag is specified, the "pipe" instruction will attempt 
execution of the external program, but failure will not cause the whole Sieve 
script execution to fail with an error. Instead, the Sieve processing continues 
as if the "pipe" action was never triggered."

However, using the :try tag marks the pip command as successful even if it 
fails and because pipe is a disposition-type action the implicit keep is 
cancelled, resulting in the piped message being discarded. If this is the 
intended behaviour then I would suggest amending the text of the specification 
to:

“When the ":try" tag is specified, the "pipe" instruction will attempt 
execution of the external program, but failure will not cause the whole Sieve 
script execution to fail with an error. Instead, the Sieve processing continues 
as if the "pipe" action was executed successfully and cancel implicit keep.”

If this is not the intended behaviour then please consider this a bug report, 
with my apologies for not adding a patch (it seems to be a bit more complex 
than just changing the return value of act_pipe_commit).

Kind regards,

Probably "client_flags" is what i need to use but:
1. i don't know the int value for CLIENT_SSL (and mysql docs arent'

This has nothing to do with mysql connection.

What i've asked for is how to tell dovecot to connect to a mysql
server by using an ssl connection (the native mysql ssl connection),
not how to enable ssl in smtp/imap/pop3/whatever

Gandalf,

Yes.

https://dev.mysql.com/doc/refman/8.3/en/using-encrypted-connections.html

It's common practice.  From my experience most LAMP stacks are built and 
with a web front end that's handling the SSL traffic via apache to 
secure the connection between the client browser and the web server.  
SSL is operating on layer 4 of the OSI model so theoretically all 
applications (and most do) have some support for encrypted connections.

Hi,

Dovecot version is 2.3.19.1 (9b53102964) running on fully up-to-date Debian 12
(Bookworm) operating system.

For the life of me I cannot figure out how to get sieve scripts working
correctly in a central directory location. Calling them from users’ home
directories works fine (as described below).

(Note: This system has recently been migrated from Cyrus IMAP, so some of the
directories for a central location are very similar to what would find in a
standard Cyrus IMAP installation.)

If I set `sieve` to its default value of `file:~/sieve;active=~/.dovecot.sieve`
in `conf.d/90-sieve.conf`, sieve works as expected. I have a file
`~/sieve/default.sieve` and, as per documentation, I make a symbolic link
`~/.dovecot.sieve` that points to that file. The sieve script runs, and I see a
`default.svbin` either created or updated in the ~/sieve directories as emails
arrive.

Setting `sieve` to `file:~/lib/sieve;active=~/.dovecot.sieve` also works as
expected. So this verifies I can change the directory where sieve scripts are
stored.

However, if I then set `sieve` to
`file:/var/spool/dovecot/home/%1n/user/%n/sieve;active=file:/var/spool/dovecot/home/%1n/user/%n/.dovecot.sieve`,
again a `default.sieve` in each of these user’s centralized `sieve`
directories, sieve scripts silently fail to run. No messages of any kind found
in any log files.

I don't believe that the active option can take the "file:" prefix.

John

So, with the same exact same configuration as one that is the default and as
proven to working, with the single exception of changing the top-level
directory (TLD) for the scripts, results in silent failure. Why?

What I find particularly odd is that if I keep `sieve` set to this central
directory location (i.e., no config changes), and `mv sieve/default.sieve
sieve.tmp; rmdir sieve; mv sieve.tmp`, that is, have a *file* called `sieve`
where the setting `sieve` points to (which, per docs and experience, should be
a *directory*), the users’ sieve scripts *do* run, but with a warning along the
lines of `Warning: sieve: file storage: Explicitly specified active script path
`file:/var/spool/dovecot/home/m/user/morse/.dovecot.sieve' is ignored; storage
path `/var/spool/dovecot/home/m/user/morse/sieve' is not a directory`.

In the docs I see that `sieve` used to refer to a file (PidgeonHole Sieve
v.0.31 or prior, I believe), and there is mention of a a `sieve_dir` setting
(which I have *never* set or used). So my guess is that sieve working in this
centralized TLD with `sieve` as a file rather than directory is due to support
for some deprecated config / functionality.

I have fiddle around with this for some hours, including setting and not
setting `mail_home` to the central directory location (i.e., `mail_home` in
`conf.d/10-mail.conf` set to the same value as `sieve` in
`conf.d/90-sieve.conf`),to no avail. No matter what I do, I cannot get sieve
scripts to run in a centralized directory location as they do under `/home`.
The only exception is as just described in the preceding paragraph. But the
solution only allows a user to have a single sieve script, and I imagine
`managesieve` will not work properly is sieve is set up as described in the
preceding paragraph.

What am I missing or doing incorrectly?

Any and all assistance most appreciated.

Re: Pigeonhole Sieve only runs scripts if in users' home directories, or if Sieve is purposely broken

2024-05-15 Thread Douglas Morse via dovecot


Apologies, just to be completely explicit, I should have stated that of course 
in every configuration I mentioned the `.dovecot.sieve` file always pointed to 
the user’s main sieve script, wherever I may have placed it at the time.

So for example my centralized configuration is as follows when mirroring the 
default configuration but in a non-home top-level-directory (TLD):

/var/spool/dovecot/home/m/user/morse/.dovecot.sieve -> 
/var/spool/dovecot/home/m/user/morse/sieve/default.sieve

which does not work, and as follows when it does (with the warning that 
specified sieve location is a file rather than a script):

/var/spool/dovecot/home/m/user/morse/.dovecot.sieve -> 
/var/spool/dovecot/home/m/user/morse/sieve

lda-dupes-file not updated, when user over quota and sieve vacation enabled

2024-05-14 Thread Christian Rößner via dovecot

Hi,

we have encountered an interesting behavior with users that have their 
mailboxes over quota while having sieve-vacation enabled. We do a temp fail, if 
a mailbox is over quota.

Problem:


If a remote sender sends an email to such a user (over quota + vacation), 
Dovecot directly creates a response message and sends it back to the sender. So 
far so good. At the same time the original email cannot be stored in the users 
INBOX, which leads to a temp fail action. Now the email remains in a queue and 
whenever the queue manager tries to deliver the email again, the behavior 
starts again. Send vacation response and temp fail, until either the queue life 
time exceeds or the user has cleaned up his/her mailbox and the message can be 
stored.

For the remote sender it means getting lots of vacation emails from the same 
recipient. For each retry one vacation message.

Tracing:


We dig a little bit deeper and turned on logging to see what happens.

Because the email cannot be put into the users INBOX, it keeps in a failure 
state. And because of this, the dupes-file is not updated for this particular 
sender.

We are not sure, if this is a wanted behavior or not. But for a sender, it is 
really annoying to receive vacation messages on and on.

Solution:
-

Unfortunately we could not find any settings to change this. So I come here and 
ask for your kindly help. At the moment of this writing I can not provide a 
doveconf -n output, but I hope you trust me that we have not done too many 
things wrong ;-)

  fts_lucene = whitespace_chars=@.


}

&

protocol sieve {

basically

sieve_duplicate_default_period = 1h

OK, let me rephrase the problem:

I want to keep a copy of an email in Inbox and put a copy into another
folder, but only once, even if I run sieve-filter as above multiple
times. I know there are many who know how to do this and I would really
appreciate your generous suggestions.


The sieve-filter tool was mainly created to mend mailboxes after 
failures in sieve execution at delivery time. It currently does not 
provide access to the duplicate database and any actions that operate on 
it are ignored.


What exactly are you using sieve-filter for? Why are the Dovecot LDA or 
the Dovecot LMTP service with the Sieve plugin not fulfilling your needs?

Stephan.

I see.

But I wonder if there is something wrong with what I already have. It worked 
fine for years, and it works fine for most of my users. I tested with a few 
accounts, and Archving (with its sa-learn script) works blazingly fast. But 
with one user - happens to be mine - it is super slow when archiving, most 
likely due the sa-learn.

Best,

Francis

Yep. See

you can filter by mechanism.

The weird thing is that I get this still:

May 09 21:45:47 auth: Error: oauth2(myu...@mydomain.com,48.237.124.127): oauth2 
failed: Introspection failed: No username returned

Even when I have my configuration like this:

passdb {
   driver = oauth2
   mechanisms = xoauth2 oauthbearer
   args = /etc/dovecot/dovecot-oauth2.conf.ext
   result_failure=return-fail

What could be the cause?

Thanks Benny. Using spamc and sa-learn isn’t a bit the same? But I’ll check the

If you want to analyze emails, why not do it with scheduled crons 
after they are archived?


maybe ask for skip older then one day in here

while roundcube just set the needed flag for retest ?


wouldn't it reanalyze all archived messages anyway?


sometimes email is ham at recpt stage, while its spam later on test,

No you should add search filter for messages like from today, this week or so.

I see that yeah, sa-learn takes a little while to execute. But maybe the issue 
is that Dovecot doesn’t seem to release the IMAP connection until each message 
went through sieve. This gives me some timeout on Roundcube (it says just

It means that introspection did not return username for the token. This 
is important, because if the token is not validated to belong to the 
user attempting to log in, anyone could login as anyone with any token.

Actually, the problem was not that. It was some change on Dovecot where 
suddenly I need to add "clientid:client_secret@" on the url (googled it, 
and saw that you advised that before). Now it works.

OAUTH2 problem when migrating to Ubuntu 24.04

Re: Failing to archive many messages

2024-05-09 Thread Francis Augusto Medeiros-Logeay via dovecot

I noticed that my sieve rules are taking a very long time when archiving 
messages. I can see on my logs that every message takes about two-three seconds 
to be evaluated. 

My sieve for the Archive is this:

cat /var/mail/vmail/mail/sieve/global/report-ham.sieve
require ["vnd.dovecot.pipe", "copy", "imapsieve", "environment", "variables"];

if environment :matches "imap.mailbox" "*" {
  set "mailbox" "${1}";
}

if string "${mailbox}" "Trash" {
  stop;
}

if environment :matches "imap.user" "*" {
  set "username" "${1}";
}

pipe :copy "sa-learn-ham.sh" [ "${username}" ];

And my sa-learn-ham.sh is this:

#!/bin/sh
export PATH="/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin:$PATH"
exec /usr/bin/sa-learn -u ${1} —ham

Re: Namespace configuration for archive in different storage

Hi guys any help for that?

Hi guys,
At the moment i was able to configure the namespace for reading mails in the
second storage.
However, Thunderbird cannot access the 'cur' folder inside the user's Maildir
(inside the second storage); instead, it only sees a ghost folder with the
namespace prefix.
So, currently, the client can view all subfolders inside the Maildir folder,
including Trash and Drafts, but not 'cur'.
To be more specific, my plan is to obtain a clone of the Inbox for archiving
mails on a different storage where the Inbox is hosted.
Is my namespace configuration right?
Thank you.

In complicated, localized authentication scenarios, Lua auth is likely the best 
answer.

Hi Marc,

Hahaha, yea well, galera served us well until now, and assuming no DDL 
changes on large tables we believe it will continue to do so.  That 
aside, I do like ldap indeed, but unfortunately that's not a feasible 
option at this stage.



What I'm hoping is that dovecot has some way to in case of such
"authentication backend" problem scenarios to ignore protocol and
politeness and simply disconnect the client, ie, just shut the
connection without saying anything, this could even be with a small
delay (I'd say 1 second or so, just to avoid tight auth retry loops, up
to 4 or 5 seconds IMHO would be fine).

auth_failure_delay = 2 secs ?


That will still simply wait before *rejecting* the login, compared to 
*dropping the connection*.


We are thus looking for three different behaviours:

1.  If backend confrims auth, ACK auth + proceed (grant access) to email.

2.  If backend confirm "no such user" or "invalid creds", wait for 
auth_failure_delay and then *reject* the login.


3.  If the backend fails (ie, can neither confirm nor deny), simply drop 
the connection.


I hope this is more clear.

Kind regards,
Jaco

temporary auth errors

2024-05-02 Thread Jaco Kroon via dovecot


Hi All,

Looking for some advise.

We ran into a situation yesterday where our SQL cluster (mariadb-galera) 
stopped serving requests due to some DDL queries locking the wsrep 
provider.  We're addressing this separately, so just background as to 
the cause of the problem.


As far as I know both POP3 and IMAP protocols only have two possible 
responses when a user tries to authenticate, either ACK (yes, you're 
fine let's proceed) and NACK (no, something with authentication failed, 
and either you've got credential issues, or something is wrong with the 
backend).


An ACK results in granting the user access.

A NACK results in the user having to retry.

This is all good and well, but the *typical* response by a MUA is to 
re-prompt the user for credentials, to which the response is usually to 
retry random passwords until it works again (confirmed with Outlook and 
Thunderbird).


What I'm hoping is that dovecot has some way to in case of such 
"authentication backend" problem scenarios to ignore protocol and 
politeness and simply disconnect the client, ie, just shut the 
connection without saying anything, this could even be with a small 
delay (I'd say 1 second or so, just to avoid tight auth retry loops, up 
to 4 or 5 seconds IMHO would be fine).


The hope is that this will result in the mail client treating this like 
a connection error rather than an authentication error, and hopefully 
not prompt for new credentials, but simply an alert of the "there has 
been a problem communicating with your mail server please retry or 
contact your service provider" kind of error messages.


For reference, the errors in dovecot logs looks like:

May  1 04:42:25 uriel dovecot[352]: auth-worker(11615): Warning: 
sqlpool(mysql): Query failed, retrying: WSREP has not yet prepared node

2024-05-01 Thread Francis Augusto Medeiros-Logeay via dovecot

Hi,

When I archive one or two messages, the messages are correctly moved to the 
Archive.

However, when I archive more messages - like 50 or more, dovecot seems to fail. 
The error I get is this one:

 Warning: Failed to do incremental sync for mailbox Archive, retry with a full 
sync (Modseq 17277 no longer in transaction log (highest=17323, 
last_common_uid=12216, nextuid=15767))

No messages end up being moved to the Archive folder. I tried to do this both 
from a mail client and from roundcube.

What could be the problem here?

ENV{"PATH"}. errors on my log

2024-05-01 Thread Francis Augusto Medeiros-Logeay via dovecot


Hi,

I'm getting this error a lot on my logs:

May 01 12:57:03 imap: Error: Use of uninitialized value $ENV{"PATH"} in 
split at /usr/lib/x86_64-linux-gnu/perl-base/File/Spec/Unix.pm line 136.


I googled a bit and the only reference I found was related to the 
possibility of imapsieve scripts that could be generating this. I 
haven't found any perl script on my install, but I momentarily turned 
off spamassassin, but the logs continued.


Any hint on how I can debug this? Turning the debug logs on dovecot 
didn't bring me any extra information of what the source of this could 
be.


Best,
Francis

We have a migration guide at https://doc.dovecot.org/admin_manual/
migrating_mailboxes/
 
This should help you out. If mailboxes are compressed/encrypted and they work
today, no need to do anything about them.
 
Important thing is to try out with test account(s) first.

 ignore it. AFAIR dovecot is using some linux-mechanism (epoll?),
 which
 is no part of freebsd.

Has nothing to do with epoll. Dovecot uses kqueue on FreeBSD. This indicates
clock issues, you should use ntpd to avoid this, alternatively your VM/machine
is lagging and clock is jumping forward.

doveadm import will happily import same emails over & over again. It has no 
such check. You should use doveadm sync -1 instead. (-1 = one way)

Re: doveadm backup has problems with some accounts

2024-04-29 Thread roger.meier--- via dovecot

Because, that perhaps the version missmatch of the servers coul'd be the issue 
, and centos 7 eol comes in two months, i setup a complete new main mailserver, 
based on
ubuntu 22.04 (24.04 was not out on starting to setup the stuff) so now both 
servers had dovecot 2.3.16.

But it doesn't help, still the backup jobs abort in the middle of the transfer, 
now with complete different error messages.

On the destination server i started it with the following command ( the 
corresponding user folder & files is deleted under /var/spool/vmail and 
/var/indexes )

/usr/bin/doveadm -D -v backup -t 1200 -Ru user1 tcp:mua02.domain.intra:12345

Dovecot Server issue, cache corruption

2024-04-28 Thread David Mehler via dovecot


Hello,

I'm using Thunderbird 102 to atempt to retrieve my messages via imap 
(have tried both 143 and 993) first I wasn't getting any error messages 
now I am. This is with Dovecot 2.3 on Debian 12.5. Here's the error 
messages. I do not believe the first set related to public mailboxes is 
related but I'm not sure what it's problem is either, the problem seems 
to be corrupted cache.

I have a file backup and since that backup, new emails have been 
received. Also, not all of the emails were deleted - many folders 
weren't affected. Additionally I was able to restore a few of the 
deleted emails with ext4magic.


So now I have three sources:

1. MAIN (new dovecot) contains the emails in the folders that weren't
   deleted and the emails received after the incident.
2. BACKUP (of mail directory) contains all emails from last backup date
   (including those still in the folders that weren't deleted).
3. RECOVER (directory) contains deleted email files that were recovered.

How can I join these sources into MAIN,

 * without deleting any emails from MAIN (for example those that have
   been received today) and
 * with only reading and not writing into BACKUP and RECOVER?

Is there any more or less convenient way to achieve that?
If not, can I just dump all the files together and make dovecot recreate 
the indexes?

I don't really get what is going on with remote host. How is a host name even 
relevant other than setting up the initial connection. I don't even see it in

Hello,

I'm relative new to oauth2. I like to understand a setup for dovecot but 
https://doc.dovecot.org/configuration_manual/authentication/oauth2/ is not 
enough for me.
Could anybody describe a simple setup where dovecot uses keycloak. For 
simplification I would start with keycloak's builtin user management only.

- how to configure dovecot
- how to configure keycloak
- how to test with 'curl --verbose --some-magic-options imap://dovecot-server'

Hello Dovecot Dev team,

  


In my cpanel, we use your email management. This is what my hosting provider
has allowed.

  


Our problem:

Since the introduction of "hi def cameras on mobile phones", we are getting
emails with "huge attachments". The email which comes with the attachments
is also important. However, once we download the email (imap), using any of
the email clients (outlook, bluemail etc.) the mailbox still has these huge
attachments. Because of this, our mailbox storage gets filled up quickly. In
our email client software, we can delete (attachments only), and leave the
email in our mailbox. So this work around helps us keep our mailbox size
manageable. Unfortunately, not everyone does this "email attachment cleanup"
regularly and end up being locked out of email storage space and probably
lost a few hours of productive time.

  


Our dev Request:

Would it be possible to create a setting for end users in our Cpanel, in
which we can delete the attachments without deleting the actual message?

So query should have:

 (drop down selection, like you have it now)

*   Filter 01: Select Messages older than nnn days (where nnn would be
100 to 999 days) (so for the first 99 days, every imap client would have the
opportunity to download the email and the attachments)
*   From Filter 01 = Filter 02: Select messages which are >xxx Mb (where
xxx could be 001 to 999 Mb)
*   From Filter 02 = Filter 03: Select only messages which contain
attachments (Yes)
*   From Filter 03: Permanently Delete the attachments ONLY, So not
deleting the actual email msg (OK).

So on day 100 (or after the clean up is done), the imap email client will
now only get the email but not the attachments (in the event they need to
refresh their email setup).

  


If such a query can be created and installed on our Cpanel, we can run this
"clean up attachments" query regularly and as such reduce our mailbox size.

  


Q: Would it be possible to create such a clean up tool (pre-defined) so that
the cpanel web service admin user only has to enter (nnn and xxx and Yes) to
finally click on "OK" to delete the attachments?

  


If this would be possible, what will it cost us to have it installed on our
Cpanel?

  


There is so much information/documentation already on your website
(doc.dovecot.org) and I spent about 60 min looking for such a "clean up
tool" documentation, but started getting dizzy reading all that script
language etc. Not my cup of tea.

  


Please help.

  


Thank you for considering and reading this request.

  


Kind regards

I cannot semantically argue with your wording, they are indeed both
"part of the authentication credentials.",but usernames are
IDENTIFICATION, not AUTHENTICATION.

And in the same way you do not have a case sensitive name,  you should
not have a case sensitive username.   (Society's convention is that
your name is capitalised in Proper Noun format, from a information
technology perspective, all lowercase is the same convention).

You should look at *lots* of DMARC RUA reports.  People are doing crazy batsh*t
stuff with your mail domain.

Re: Which DKIM application for postfix 3.9.0

2024-04-24 Thread Jean-Daniel Dupas via dovecot

Talking about completeness, you can also use rspamd (https://www.rspamd.com 
).
While it it design to to more than DKIM, it can be use for it.

I have an internal mailer relay based on postfix and rspamd that works great.

Logging e_debug messages

2024-04-23 Thread D S via dovecot

Is it possible to log the e_debug events in quota-status.c? 
[https://github.com/dovecot/core/blob/main/src/plugins/quota/quota-status.c]

Running: Dovecot 2.3.19.1 (9b53102964)

Here's the config I've tried:

log_path = /var/log/dovecot.log

event_exporter log {
  format = json
  format_args = time-rfc3339
  transport = log
}

metric everything {
  exporter = log
  filter = event=* OR category=*
}

log_debug = event=*
auth_verbose = yes
auth_debug = yes
mail_debug = yes


This seems to capture events at INFO level or higher, and some Debug log 
messages, but not the e_debug messages in quota-status.c.

Thanks,
Daniel

i do dkim signing in amavisd, and dkim reporting from spamassassin, lots

hope arc will be supported in next amavisd

I can remember looking at rspamd years ago. I thought it was a bit chaotic with 
all these rules. I can even remember asking developers some design questions 
which they could not answer. The fact that they generate their own graphs 
(still?) is also old fashioned. This Sergey that is working on mailfromd is an 
ace with mta's, even implemented for me an exporter endpoint, so now I can 
chart whatever I want.

The developers of DKIM moved on to ARC, then they stopped working on ARC also.

Sieve: Avoiding duplicates in a folder while keeping in Inbox

2024-04-22 Thread Nick Urbanik via dovecot

Dear Folks,

I am in the process of learning Sieve, and want to be able to keep an
email in Inbox, while also keeping *one* copy in another folder. 
However, the same mail is copied from Inbox multiple times when I run
sieve-filter -Wev .dovecot.sieve Inbox

My attempt to prevent this fails:
...
} elsif header :comparator "i;octet" :contains "From"
"pay...@paypal.com.au" {
if not duplicate {
fileinto "paypal";
}
keep;
}

Please can anyone enlighten me?
