[Dovecot] per-network auth mechanisms
by George Moury 27 Jan '07

27 Jan '07

Hi All, I need use different auth mechanisms for different IP-address of IMAP/SMTP SASL clients (allow plain authorisation only for my own network), but there is no examples at wiki.dovecot.org for this feature. Is this feature available at rc19 version? Thank you in advance. Best regards, George

[Dovecot] Advice, Converting a Live/Production server.
by Michael Dilworth 26 Jan '07

26 Jan '07

I want to mess with a live server. (a Bad thing). I have googled until my eyes boogled, wiki'ed until my fingers are wonked, have read as much as I can read, however I'm left with a few questions/worries. Issue: I am currently running Dovecot as a pop3 server with standard /var/mail mbox's I would like to run a mixed Imap/Pop3 server with ~/maildir inbox's The thread http://www.dovecot.org/list/dovecot/2006-February/011304.html is fairly close to what I want to do, but I would like to go ahead and convert to maildir. (Mixed pop3/imap access for each user) I don't have a system to test, "I used have one but it's now the production server... PW/Disk failed, thank G-D(s) for rsync/backups". Setup: procmail, dovecot 1.0 beta 8.2 (fc5), squirrelmail. all users use outlook (2000,2003) or outlook express (random versions) (^^^^ not my choice, I just have to deal with it {and use it} ^^^^^) the majority of users will continue to use pop3, however some would like to convert to imap and have all mail stored on the server. Questions: /etc/procmailrc? just set default to ~/maildir? do I need to define "INBOX"? aka $MAILDIR=~/maildir/, $ORGMAIL=~/maildir/, $DEFAULT=~/maildir/ Same as above, what about new/cur should I set up a /etc/skel? close to above, if I create rules, for spam, etc. do I need to worry about cur/new. close to above, what about Sent Items, Drafts etc... for imap users, I do understand that client rules would likely be needed to store sent items. conversion, anything to look for? mb2md seems to work, but some users have "don't delete from server set", will they get dups? (I can live with this) archiving, can I (or a script) mess with the files in the maildir? aka keep the number of files/messages less than 16k for the outlook users. Bugs, should I cool my heals, and wait for rc16 or 1.0 final? I am currently running problem free, and I do hate to mess with something which is not busted. TIA Michael.

[Dovecot] Dovecot POP3 fails to chdir under FC6
by James A. McDonald 26 Jan '07

26 Jan '07

I started the Dovecot POP3 server under Fedora Core 6 (rpm dovecot-1.0-1.1.rc15.fc6), but some users couldn't connect, with /var/log/maillog show the message Jan 24 13:20:00 mmace dovecot: chdir(/branch/home/mmace) failed with uid 205: Permission denied Jan 24 13:20:00 mmace dovecot: child 18792 (pop3) returned error 89 (I had already edited first_valid_UID in /etc/dovecot.conf to allow UID's >= 200.) However, only users who had their home directory under /branch/home couldn't connect. Users with homedirs under /home connected via POP3 just fine. I found out POP3 connection failures also logged an error to /etc/messages: Jan 24 13:20:00 mmace kernel: audit(1169662800.479:160): avc: denied { search } for pid=18792 comm="dovecot" name="/" dev=sda3 ino=2 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:mnt_t:s0 tclass=dir So, selinux was the culprit. My home directories had the right selinux security context, but the root of the disk holding those home directories (/branch is a separate disk drive) had a security context (system_u:object_r:mnt_t) that Fedora's selinux rules for dovecot did not allow. I changed the context of /branch to system_u:object_r:usr_t, and dovecot POP3 access worked for all users.

[Dovecot] X-UID gaps cause Dovecot/IMAP to hang
by Benjamin Howell 25 Jan '07

25 Jan '07

Hi, When the Dovecot 1.0.rc19 IMAP server encounters X-UID headers with gaps in them, it hangs indefinitely. I've attached a sample mailbox (in mbox format) which repeatably exhibits this behavior. The mbox contains only three messages with the following X-UIDs in order: 774, 785, 787. If I remove the X-UID headers from each message, Dovecot handles the mailbox without any problems. UW-IMAP is able to handle the sample mbox _with_ X-UID headers. A full backtrace is also included. When Dovecot hangs, it appears to continually lock and unlock the mailbox. I'm using dotlocking so a mailbox.lock file appears and disappears constantly. I have to kill the process to log back in. I'm not familiar enough with Dovecot to offer a patch, but if anybody feels they can fix this or needs more information, please let me know. Regards, Benjamin Howell bhowell(a)iglou.com

[Dovecot] rc18->rc19: read/unread/reply flags broken
by Jeff A. Earickson 25 Jan '07

25 Jan '07

Timo, This might be a bit vague, but I have noticed that rc19 seems to have broken the read/unread/reply flags in imap. My officemate has had problems with messages that are read and marked as read then mysteriously get remarked as unread the next time email is checked. I've had problems where I reply to a message and it does not get marked as "answered". We didn't see this with rc18 and earlier. My setup: Solaris 10, sparc, T2000 system. rc19 (now back to rc18), using mbox format. system mailbox is NFS mounted from another Sun Solaris 10 system, homedirs and dovcot cache files are on local zfs filesystems.
