To be clear: Accessing same mailbox from different IMAP servers __at the same 
time__.

The most important part of Director is it makes sure same mail user always 
proxied to same backend IMAP server.

If mailbox is in Maildir format (and stored on shared storage like NFS), 
accessing it from different server may corrupt Dovecot index files and mailbox 
becomes unaccessible. Director perfectly avoids this issue.

HAProxy can proxy mail user from same client IP to same backend IMAP server, 
but not same mail user from different IPs.

Quote (https://doc.dovecot.org/admin_manual/director/dovecotdirector/):

"Director can be used by Dovecot’s IMAP/POP3/LMTP proxy to keep a temporary 
user -> mail server mapping. As long as user has simultaneous connections, the 
user is always redirected to the same server. Each proxy server is running its 
own director process, and the directors are communicating the state to each 
others. Directors are mainly useful for setups where all of the mail storage is 
seen by all servers, such as with NFS or a cluster filesystem."

Director is used when you setup frontend servers in a load-balance cluster, 
proxy imap/pop3/lmtp/managesieve requests to backend Dovecot servers.

I setup load-balance cluster for clients with HAProxy + KeepAlived + Dovecot 
Director running in frontend servers, so sad we have to find an alternative to 
replace Director in such case.

It's not about "small/medium" servers, but the demand of imap/pop3/lmtp proxy 
service, especially in load-balance cluster.

The document is for iRedMail, it supports storing mail accounts in SQL or

Dear Andre,

Thank you very much for the input.

Post login script should work as you suggested, but consider Dovecot already 
supports "allow_nets=a.b.c.d", we just need a mark like "!" to exclude some 
IP/networks, this might be the best and most elegant solution (if it can be 
implemented, of course), because we need only one userdb/passdb for all users, 
just different "allow_nets" for access control. Not one userdb/passdb for one 
each access policy.

Dear Sami,

Thank you for the suggestion.

Adding more passdb is not ideal at all, if we have more access policies, we 
don't want to add more and more userdb/passdb.
Dovecot already supports syntax "allow_nets=a.b.c.d", we just need something 
like "!" mark to exclude some IP/networks.

Dear Malcolm,

As mentioned earlier, this per-user access control, not for all users. This

I suppose not. We don't restrict ALL users this way, just few of them.
And the client IP addresses may change frequently, not static IPs.

I understand what "allow" means. But it will be very handy to support something

Feature request: exclude IP/network in allow_nets extra field

[Zhang Huangbin via dovecot]

Dear all,

We use `allow_nets`[1] to restrict login clients, it works fine.
Recently we need to allow some users to login from everywhere except some 
IP/networks, how can we accomplish this with "allow_nets"?

Tried allow_nets="!a.b.c.d", but Dovecot reports error "allow_nets: Invalid 
network '!a.b.c.d'".

Can we have this feature?

i guess it should be done in function "auth_request_validate_networks"[2] in 
file src/auth/auth-request.c.

According to Dovecot source code[1], only MySQL has the "ON DUPLICATE KEY"
support, this is out of date because PostgreSQL has similar feature ("ON 
CONFLICT")[2]
since version 9.5. Also:

- Debian 9 ships PostgreSQL-9.6.
- Ubuntu 18.04 ships PostgreSQL-10.6.
- openSUSE tumbleweed ships PostgreSQL 10 and 11.
- Although CentOS 7 ships PostgreSQL 9.2 (NOT CAPABLE), but RHEL 8 public beta
  already ships PostgreSQL 9.6 and 10.
- OpenBSD 6.4 ships PostgreSQL 10.5, upcoming OpenBSD 6.5 ships PGSQL 11.2.
- FreeBSD ports tree offers PGSQL 9.5, 9.6.

Seems latest mainstream Linux/BSD distribution releases are all ok to use this
"ON CONFLICT" support, the question is, can we have this feature in Dovecot for 
PostgreSQL?

Thank you very much for the help. :)

BTW, SQLite has similar feature since version 3.24.0.

Dear all,

Some suggestions:

- should replace log() by the standard logging module like "logging.debug(xx)”
- add managesieve support
- add lmtp support
- how about store command line options in a config file? remove the ‘optparse’ 
module.
- email notification support when server is up/down
- lots of PEP8 style issue :)

My concern is, will you experience any lag while moving message?

According to the doc, this plugin works like “pipe” backend of old “antispam” 
plugin, when you move a message from INBOX to Junk, the antispam plugin calls 
sa-learn, and you will experience noticeable lag on webmail (i used Roundcube 
webmail for testing) until sa-learn finished. It's much worse if you move 
multiple emails at the same time, because we have to wait for sa-learn to learn 
all moved messages.

I switched to “spool2dir” backend of old “antispam” plugin, and call sa-learn 
hourly to learn spam/ham. Since it simply copies moved message(s), no lag on 
webmail side at all, our users are satisfied.

All logs during the telnet testing session:

dovecot: Nov 03 20:45:45 Info: pop3-login: Disconnected (no auth  
attempts): rip=192.168.187.1, lip=192.168.187.128

2) Log in with telnet to see what exactly it's writing.

It seems works fine:

After telnet testing, i use Thunderbird to test it again, but it  
failed with same error message i posted in previous mail:

Is it OK?

[Dovecot] Post login script issue with pop3 protocol

[Zhang Huangbin]

Hi, all.

I want to track user last login data (ip address, login date, etc)  
with dovecot, followed dovecot tutorial[1], and it now works with  
IMAP, but failed with POP3. i don't know why.


My script:

LDAP_URI='ldap://127.0.0.1:389'
LDAP_BASEDN='o=domains,dc=iredmail,dc=org'
BIND_DN='cn=vmailadmin,dc=iredmail,dc=org'
BIND_PW='plain_passwd'

if [ X${USER} != Xdump-capability ]; then
ldapmodify -c -x \
-H ${LDAP_URI} \
-D ${BIND_DN} \
-w ${BIND_PW} EOF
dn: mail=${USER},ou=Users,domainName=$(echo ${USER} | awk -F'@'  
'{print $2}'),${LDAP_BASEDN}

changetype: modify
replace: lastLoginDate
lastLoginDate: $(date +%Y%m%d%H%M%SZ)
-
replace: lastLoginIP
lastLoginIP: ${IP}
-
replace: lastLoginProtocol
lastLoginProtocol: pop3
EOF

fi


It works with IMAP protocol, but failed with POP3 protocol.
Error msg in Thunderbird:

The STAT command did not succeed. Error getting message number and  
sizes.

How about giving the imap or pop3 as parameter? You're already  
modifying

mail_executable, so:

protocol imap {
 mail_executable = script.sh imap

protocol pop3 {
 mail_executable = script.sh pop3

It works with above setting. Thanks Timo :)

[Dovecot] Best way to get login protocol (pop3/imap) in post-login script

[Zhang Huangbin]

Hi, all.

I found doc here: http://wiki.dovecot.org/PostLoginScripting
and use ${USER}, ${IP} to track last-login username and remote ip  
address, but how can i track the mail protocol it used? like pop3,  
pop3s, imap, imaps?


Currently, i wrote shell script as post-login script, and use below  
command to get protocol:



$(basename ${MAIL_PLUGIN_DIR})


But is it the best way to get it?

Thanks very much. :)

Why is this happening?



You should set 'mail_debug = yes' in dovecot.conf, and you will find  
out why in its log file.

Do you mean '((objectClass=posixAccount)(uid=%u)(ou=%d))'? or 
'((objectClass=posixAccount)(uid=%u))'?


Or you can just use '(objectClass=posixAccount)' for test.

[Dovecot] How can i override mail_location?

[Zhang Huangbin]

Hi, all.

I use dovecot-1.1.11 with OpenLDAP backend. but i found the
mail_location is not correct. How can i override mail_location setting
in dovecot.conf?

LDAP user data and dovecot config are attached below. in dovecot config,
mail_location is:

mail_location = maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/


but the correct maildir should be 'homeDirectory' + 'mailMessageStore':

maildir:/home/vmail/a.cn/w/ww/www/

setting in dovecot.conf:

mail_location = maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/



Also home directory should be different for each user, so you most
likely don't want to set homeDirectory=home.
  

I will try to change this, thanks Timo :)

hi, Timo.

Any suggestion about these LDAP attributes:

homeDirectory
mailMessageStore

Both are absolute path? like /home/vmail/a.cn/w/ww/www/ or what?

Need to add more attributes? How about mailbox INDEX?

[Dovecot] Performance issue about maildir path.

[Zhang Huangbin]

Hi, all.

Normally, i use 'domain.ltd/username/Maildir' as users' maildir path, if
i change them to hash style, e.g. 'A0/B0/domain.ltd/C0/D0/username/Maildir',
will it speed up the index operation for MDA? If we have 1 users,
which maildir path style will improve performance?

Yes, this would be a nice feature. But currently it's hard coded, so you

I'm just guessing - but reading that warning it appears to me that 
Dovecot is saying that as it is configured, it can consume more O/S 
resources (I assume fd is file descriptors) than the O/S is 
currently configured for.  So you need to DECREASE your dovecot max 
processes to decrease the (potential) system demands - or increase 
your O/S settings.


Daniel



I think so.

I just decrease the processes, it works now.



Hi,

Just as an FYI, for some versions of linux (i.e. RHE) you need to set 
the process limit - ulimit unlimited is not enough. 1024 is the 
default number of open file descriptors.


One of the ways to solve this is by running 'ulimit -n X' in your init 
script before starting the program. Within RHE, another way is to 
configure /etc/security/limits.conf by putting something like this 
into the file:


*hardlocks 8192
*hardnofile8192
*softlocks 4096
*softnofile4096

This allows for processes to run with 4096 file descriptors by default 
and the user process can increase it to 8192 via ulimit. 
/etc/security/limits.conf can also be configured on a per user basis 
which is also nice.



Thanks Jack. I will test it later. ^_^

I just comment the 'max_processes' variable in dovecot.conf now.

[Dovecot] How can i set vacation subject in non-english characters?

[Zhang Huangbin]

Hi, all.

I have implemented vacation via dovecot sieve. but how can i use
non-english characters in vacation subject?

Thanks very much.

This is my sample sieve rule for vacation:

8
require [vacation];

vacation
   :days 1
   :mime
   :subject Auto-Reply: Out of office.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

I can use non-english character here as mail body, wrote in utf-8.

The same way as in all other email messages: MIME encode it. Perhaps
Dovecot should do this internally, but for now it doesn't.

Easiest way I can think of to generate the subject would be to let your
current MUA do that. Send yourself the subject you want and copypaste
the Subject: header from the raw message sources.

  

Got it. Thanks Timo. :)

Hope dovecot will do that in the future version.

Hi, all.

[Dovecot] [Help] quota_rule with LDAP backend, dovecot-1.1.1

[Zhang Huangbin]

Hi, all.

I use dovecot-1.1.1 with OpenLDAP as userdb. but i failed to convert
quota value as expect.

I set '10' as mail quota, and it should be '10M' as expect, but it's
not effect, dovecot always uses 'quota_rule' setting in dovecot.conf.

How can i fix this issue? 10*1047576?

I have 'mailQuota' attr in ldap schema, such as:

8
mailQuota: 10   # - 10M
8

My dovecot-ldap.conf:

8
user_attrs = 
homeDirectory=home,mailMessageStore=maildir:mail,mailQuota=quota_rule=*:bytes=%$

8

And my dovecot.conf:

8
plugin {
   quota = maildir

   # Quota rules.
   quota_rule = *:storage=10M
}

I use OutLook Express on Windows XP as MUA, login username is in upper case,
such as '[EMAIL PROTECTED]', when login via imap, dovecot create directories:

/home/vmail/
   |- BBB.COM/ # - Domain name
   |- AAA/ # - User name
   |- cur/
   |- xxx

Here, domain name and user name are in upper case.

How can i make it create directories in lower case?

Re: [Dovecot] Howto create maildir in lower case while user login viaimap/pop3?

Hi, Toms.

I have a similar problem. When mail comes to [EMAIL PROTECTED] (in 
lovercase) dovecot creates directory /vmail/domain.com/user, but if 
user types login like [EMAIL PROTECTED], then dovecot creates dir 
/vmail/domain.com/User and I wonder why dovecot accepts the login name 
at all?


In my sutiation dovecot is auth against mysql database.


I fixed this situation, and sorry for the noise :(

Reference:
http://wiki.dovecot.org/Variables#head-010a6461d783547686f70249e820fd6b83fd453e

%L - lowercase

So i set mail_location to:

mail_location = maildir:/%Lh/%Ld/%Ln/:INDEX=/%Lh/%Ld/%Ln/

It works.
