Re: Panic: file ostream.c: assertion failed when using mail_filter on RHEL8

Hi, Mail-filter plugin was removed in version 2.3.14. Any idea why was this removed? Is there a replacement for the mail-filter plugin? Kind regards, Martijn Brinkers
Panic: file ostream.c: assertion failed when using mail_filter on RHEL8
Hi,
I installed dovecot on a new up-to-date RHEL8 test system and
configured a simple mail_filter plugin which only copies the input back
to the output (i.e., the filter does nothing special).
On RHEL8 I get the following panic when saving the mail. The Dovecot
version that comes with RHEL8 is dovecot-2.3.8-4.el8.x86_64
The mail_filter works correctly on an Ubuntu machine )2.2.33.2-
1ubuntu4.7)
Any idea what's causing this panic on RHEL8 and how to fix it?
Kind regards,
Martijn Brinkers

[Dovecot] Change in LAYOUT=fs between 1.2.9 and 2.0.19?
While testing an upgrade from Dovecot 1.2.9 (on Ubuntu 10.04 LTS) to
2.0.19 (12.04 LTS) I encountered the following change in behaviour:
In both setups, mail_location is defined as follows:
mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs
No other mail_location-related settings are set in the config.
On 1.2.9 this leads to new mail being delivered to this example directory:
/home/username/domains/example-domain.ext/webmaster/.Maildir/INBOX/new/
On 2.0.19 the exact same mail_location is set, but new mail is now
delivered to:
/home/username/domains/example-domain.ext/webmaster/.Maildir/new/
Notice the missing /INBOX/ in the path on 2.0.19.
I found no mention of this change on
http://wiki2.dovecot.org/Upgrading/2.0 which first lead me to suspect
this was a bug in 2.0.19.
However, while browsing the 2.0-wiki I found a page which sheds some
light on the behaviour that is to be expected from Dovecot 2.0.x. Quote
from http://wiki2.dovecot.org/MailLocation/Maildir#Directory_layout
Mailbox directory name:
Without DIRNAME, INBOX will be stored at ~/Maildir/{new,cur,tmp}/, but
when DIRNAME is specified, we get an extra path component INBOX/
immediately prior to the DIRNAME value, so in the example above INBOX
would be stored at ~/Maildir/INBOX/mAildir/{new,cur,tmp}/.
I then changed mail_location to have an empty DIRNAME, like:
mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs:DIRNAME=
It appears this fixes the problem for new mail arriving (haven't tested
other folders yet).
Questions:
1. Is this a deliberate change in behaviour between the two versions? If
so, may I suggest adding this change to the Upgrading to 2.0 wiki page,
because I was unable to find the relevant info quickly.
If not, is this a misconfiguration on my side, or a (known) bug in one
of the two versions?
2. Is the DIRNAME=(empty) a good solution, or is it unusual/hacky to
leave DIRNAME empty? Any particular problems I may expect using this
configuration?
Thanks in advance for your help.

[Dovecot] NFS Maildirs
Hi, We have our user homedirs on nfs so I enabled nfs parameters in dovecot.conf. Everything works fine but when I want to delete a homedir of a user I can't delete it because I can't remove the .nfs files in the Maildir.

Re: [Dovecot] Feature request: usernames and passwords
Op 21 jul 2010, om 15:06 heeft Leonardo Rodrigues het volgende geschreven: Em 21/07/2010 09:18, Timo Sirainen escreveu: I think this is one of the tons of different possible password policies and isn't really Dovecot's job. It really should be enforced while setting the password, not while checking it. i completly agree that dovecot is not the place for enforcing password policies nor checking them. but, still on the subject, maybe dovecot could have some features for helping sysadmins to avoid/mitigate brute-force attacks. As told, some bots tries username=password, but those fuckers (the bots) also tries lots of common passwords, 123, 1234, the username followed by some numbers, and lots of others. of course, if the provided password is not correct, dovecot denies access as it should but in those situations, logs can get pretty filled with login failed messages, specially on servers with lots of accounts. And, in some cases, after lots of tries, the bot can found the correct username/password combination. i was thinking on something like ... 1) after N tries (lets say 10 for example) of wrong username/password combinations, dovecot could start delaying the answers for wrong authentications coming from that specific IP address or IP/username, thus slowing down the brute-force attacks; 1.1) or even, after some M (lets say 20 for example) wrong username/password combinations, dovecot could ban that IP address (or IP address/username combination to avoid problem with big networks with NAT access) for XX seconds/minutes, also slowing down the brute-force attack tries 1.2) this could probably be implemented using some in-memory internal backend, so it would be absolutely independent on passdb schema and would require no modifications on passdb schema. the original message says about bot brute-force attacks, but we can be facing REAL brute-force attacks against a specific account and i think that some features to help mitigate those could indeed be interesting. And if those features exists, they could surely help on those brute-force attacks coming from dumb bots as well. it wont solve the username=password specific case, but could help on real or bot brute-force attacks. what do you think on that Timo ?

[Dovecot] IMAP bandwidth
Hi, I want to calculate the bandwidth usage of the IMAP protocol. POP3 displays a message when the connection is closed about the transfered bytes. In an old mailinglist post I found this message: http://www.dovecot.org/list/dovecot/2007-March/020478.html Is this patch integrated or is there another way to calculate the bandwidth for IMAP connections?

[Dovecot] Use bacula to do backups/restores
Hi, I'm already using Bacula for a lot of backups jobs and I also want do backup mail which is stored on a server. The mail is stored in Maildirs which a could backup at filesystem level. But when I restore such a backup strange things happen. My mail client show some mail double and most of the restored mails are unread. I think I'm missing some important IMAP things. Martijn

In my experience: Cyrus = 0 Dovecot= 100 My personal experience. Kirt I guess you've right but I can't post this answer at Cyrus mailing list. I'm just trying to have my own opinion of imap server and I already have sarcastic answer on the cyrus mailing list ! Reading the cyrus list I think the above quote might be a bit unfair and accidently crossposted? In any case I only have experience of dovecot and it's used in some larger installs such as the old webmail.us, now 11 (I believe). I think your installation is probably large enough that you might want to do a trial migration of a couple of accounts and see if migration is a problem. I'm trying to migrate my own account from cyrus to dovecot with the 2 tools which seems to fit the most my needs : cyrus2courier : Work fast and well but I must use cyrus2courier-1.5.ts and I have 2 problems with it : falg unseen (or seen if I want) for all e-mail / Sub folders of Inbox are invisibles (I see them on the File System) ! imapsync : Must add a transition configuration to dovecot in order to have user passdb file (or master user) but once done it's ok and work correctly. I've just tested a transition and I'm happy to see it keeps all flags (seen/unseen too) and timestamp but as cyrus2courier, I can't see my inbox sub folders although I could see them (full) on the File System? You need to subscribe to the folders on the new server. Certainly for all new servers I would STRONGLY recommend some sort of virtualisation option (I use linux vservers, lots of other options available). This makes it fantasically easy to boot up (say) three instances of your target software installation, perhaps all with different configuration options and compare them easily. I used this as a solution to migrate from Courier and also recently when I was migrating from 32bit to 64bit guests - essentially you spin up your new guest, get it all ready, test it like made and then in a couple of seconds you can down the live guest and boot up the new guest. I separate out all signficant data from the guest partition so try to keep the actual installations under a couple hundred MB each (even that feels bloated, but hey) and this makes it simple to boot up a copy of a guest to test some change without having to copy too much I personally picked dovecot because I worried about the horror stories I read about with cyrus. However, both are clearly the two best options available for opensource solutions right now and both are used in large installations so you should be very happy with either. With regards to functionality it would appear (I don't use cyrus) that cyrus has more admin tools to do stuff, but Dovecot is built to be more hackable, for example you can easily run a script before each (imap, etc) login and hence do some very advanced stuff through that route. Plugins also appear to be quite easy to write to extend dovecot in new directions On the cyrus list they mentioned email retention policies. Now some people are going to say that this is really a job for the MTA (postfix/sendmail/etc). However, you have some plugins which might get you partly towards solving that need, but nothing out of the box which would give you a cast iron (stand up in court) kind of archiving control. However, you can get close I think Ed W
[Dovecot] Plugin when downloading mail
Is there a way to modify mail messages when they are downloaded using a special login. eg. my normal login for dovecot is [EMAIL PROTECTED] but when I log in using [EMAIL PROTECTED] I would like to download my mail which are processed using a Perl script. The Perl script will modify the content of the message (the message body). So I don't want to change the header or IMAP flags. Martijn

[Dovecot] How many imap processes per user
Hi, I'm using dovecot for the first time on a production server (before dovecot I used bincimapd). I have a question about the number of imap (not imap-login) processes created for a user. I've seen 100+ processes for just 1 user. So far it only occurs for 1 user, other users have just 1 imap process. I now the user is using thunderbird and 2 mailclients are logged in at the same time (one workstation and one laptop). Is there an issue with dovecot/thunderbird?
