[Dovecot] nologin in auth proto version 1.1
by Kirill Miazine 21 Jan '10

21 Jan '10

I notice that the nologin parameter for the AUTH command is gone in version 1.1 of Dovecot Authentication Protocol. nologin was added in 1.1, so that authentication client could indicate that there will be no subsequent master requests to retrieve user info. Could we have nologin back please? Kirill

Hi folks, Today I setup Cacti for my environment and I was wondering if there are some templates/scripts for Cacti or SNMP I could use to gather some statistics from Dovecot. Thanks in advance. BR Chris

[Dovecot] Fastest restart of dovecot after upgrade: HOW?:
by Ralf Hildebrandt 21 Jan '10

21 Jan '10

I'm running dovecot under runit: #!/bin/sh echo '/var/core/%p' > /proc/sys/kernel/core_pattern ulimit -n 8096 ulimit -c unlimited exec /usr/local/sbin/dovecot -F (that way, together with incron, I can automatically generate the coredumps I'm posting all the time) If I apply a patch and recompile, what is the fastest way of restarting dovecot? Which part of the process structure can be killed and takes all it's children with it? ├─runsvdir─┬─runsv───ntpd │ ├─runsv─┬─dovecot─┬─2*[dovecot-auth] │ │ │ ├─1203*[imap] │ │ │ ├─64*[imap-login] │ │ │ ├─64*[managesieve-log] │ │ │ └─64*[pop3-login] │ │ └─svlogd killall dovecot? Is that guaranteed to wipe out ALL child processes as well? I had to use (at least in the past): sv d /var/service/dovecot killall dovecot killall -9 imap-login ps auxwww|grep dovecot to make sure everything would be dead... -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[Dovecot] Maildir and IMAP keywords
by Per-Erik Persson 21 Jan '10

21 Jan '10

When a user in thunderbird toggles some flags like junk, spam or something similar dovecot appends these flags form a-z to the end of the file in maildir. I have another application that also access the maildirs which gets really upset with these flags and ignore those emails. Are there any other way for dovecot to store these flags to make it compatible with other softwares?

[Dovecot] Migration from Courier to dovecot
by Werner Detter 21 Jan '10

21 Jan '10

hi list, I've just registered to the list, so please be tolerant ;) I'm currently in the process of planning the migration from courier to dovecot as POP/IMAP-Server. I'm migration from Courier 0.58 (Debian-Etch-packages) to Dovecot 1.1.13 (Debian Lenny Backport). The conversion of the Mailbox from Courier to Dovecot will be done with "courier-dovecot-migrate.pl"-script[1], which works fine. However after running "courier-dovecot-migrate.pl" the Courier-Files still remain in the Maildir. Can i just delete those Courier-specific-files or does dovecot need them somehow (do you normally get rid of these after conversion)? It's about these files: courierimapacl courierimapsubscribed courierimapuiddb courierpop3dsizelist And those directories: courierimaphieracl courierimaphieracl Can i simply delete those with "find" ? Furthermore: is it possible to convert back from Dovecot-Format to Courier-Format? Thanks in advance, Werner [1] http://www.dovecot.org/tools/courier-dovecot-migrate.pl

[Dovecot] MUA notifications on new mail in a new folder?
by Kārlis Repsons 20 Jan '10

20 Jan '10

If deliver gets run with a non-root userid like this: < | deliver -m path/to/NEWmaildir >, I wonder, is a connected IMAP MUA automatically notified, that the new message has arrived in the new folder? As I see from some experiments with Thunderbird, it has no problems with immediate notifications of new mail in previously existing folders, however, it has problems with the case of new folder.

[Dovecot] outlook 2007 can't see public folders more than 1 deep
by Frank Cusack 20 Jan '10

20 Jan '10

dovecot-1.2.9 I have a public folder using ACLs to determine who can access it. namespace public { separator = / prefix = shared/ location = maildir:/var/maildir/shared subscriptions = no } Outlook 2007 can't see any folders except at the top level. It can create them just fine, but can't see them after quit and restart. For example, I can create the folder shared/foo/bar but on restart outlook only sees foo as a folder without subfolders (no + to expand it) and doesn't see bar anymore. In fact I can delete the folder foo in outlook and then BOTH .foo and .foo.bar directories are removed on the server. When you click on foo, the error message in the mail pane is "Cannot display the folder. The folder 'foo' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure not to append '/' to its name as you create it." -frank

[Dovecot] md5_verify(...): Not a valid MD5-CRYPT or PLAIN-MD5 password
by BaQs 20 Jan '10

20 Jan '10

'afternoon list! I use mysql as userdb, which contains two type of password schemes: DES and MD5-CRYPT. I read there : http://wiki.dovecot.org/Authentication/PasswordSchemes that both are supported by dovecot. Unfortunately, dovecot keeps saying: Not a valid MD5-CRYPT or PLAIN-MD5 password when looking for a user with DES encrypted password. Is dovecot able to recognize password scheme, or do I have to do something else ? I can't add {DES} to DES passwords, as this database is used with many other softwares. Thanks a lot for your help Pierre
