[Dovecot] Does Director only work with dovecot proxy?
by Edward Carraro 23 Sep '10

23 Sep '10

I was reading "conf.d/10-director.conf" and it mentions Dovecot proxy. I've been using perdition in the past for my pop/imap proxying needs and wasn't sure if Director could also use perdition or if it only works with Dovecots proxying. Thanks!

[Dovecot] Creating 'trash' folder
by Jerry 23 Sep '10

23 Sep '10

This might well be OT; however, I thought I would ask anyway. Please keep in mind that the IMAP server is Dovecot. I have a friend who uses Becky Internet Mail <http://www.rimarts.co.jp/becky.htm> on a Windows system. There us an options under the configuration menu in Becky to create the trash folder on the server. It suggest ".trash" for the name. He is aware that I use Dovecot and wanted to know if that would actually work. He claims to have activated that option in Becky; however, the trash folder was never actually created, or at least he was unable to locate it. I was just wondering if anyone had any experience with this sort of thing. I could gather more information, but I doubt that this really has anything to do with Dovecot anyway. -- Jerry ✌ Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

[Dovecot] Plain-Text & CRAM-MD5
by Leander S. 23 Sep '10

23 Sep '10

Hi there, I'm currently running my auth against CRAM-MD5 only. But I face problems with customers who apparently have smart phones which ONLY support plain-text authentification ;( Bad - I know, but what should I do ... ;/ So my question now is: Is it possible to run CRAM-MD5 as well as Plain-Text auth together with Postfix if Postfix is using Dovecot's SASL auth service? Cause that's how my setup currently looks like - except the plain-text auth ... Thanks & Regards

[Dovecot] recursive locks
by Mike Abbott 23 Sep '10

23 Sep '10

How can a dovecot-2 plugin safely use file-locks or file-dotlocks when the processes into which it plugs handle multiple connections? (Via, e.g., service imap { client_limit = N service_count = 0 }) Dovecot's file-locks and file-dotlocks do not appear to support nesting/recursion. For instance, squat_trie_lock(). Imagine one user is connected to a single imap process twice.

[Dovecot] Expunged GUID mismatch for UID error
by Xavier Pons 23 Sep '10

23 Sep '10

Hi, we have upgraded from v2.0.1 to v2.0.3 yesterday, trying to solve the "dovecot-uidlist: Duplicate file entry" errors. Now, at the moment, we don't get these errors, but when I try to expunge mails from my trash folder I get a lot of errors: Sep 23 14:24:51 imap1 dovecot: imap(user): Error: Mailbox Trash: Expunged GUID mismatch for UID 20193: 442b5ef0c3d3bf3cf4cb619944dce8e4 vs 0431b9bee05471199fabbc05af3a87a5 (with different GUIDs, and UIDs) and the mails are not expunged from Trash mailbox. Also, I have tried with "doveadm force-resync -u user Trash" and "doveadm expunge -u user mailbox Trash ALL" but not resolve the problem... Thanks Xavier Pons

I remember someone else also had a similar (same?) problem that went away when upgrading OpenSSL.

Hello, I'm testing Dovecot 2.0. I plan to use Dovecot 2.0 with thousands of domains per server. My user base is under virtual MySQL.

[Dovecot] Sieve force SSL
by Lukas Haase 23 Sep '10

23 Sep '10

Hi, I have activated only imaps and managesieve. As sieve is running on a different port/protocol: Can I make sure that sieve can ONLY be used with SSL/TLS? As the credentials are transmitted I only offer services with SSL (IMAPS, SMTP over SSL, ...). For sieve I am not sure about this. If there is the possibility that user's credentials are transmitted in plain text I would block the port from the firewall, else I would offer my users the feature to change their rules with their own client (e.g. Thunderbird sieve). Regards, Luke

[Dovecot] Dovecot LDA, virtual users, multiple uids: No luck
by Toni Mueller 23 Sep '10

23 Sep '10

Hi, I'm trying to get Dovecot's deliver to create and use mailboxen with one uid per user. Reading the wiki, I decided to go with the sudo attempt, but I'm stuck because deliver fails to create the intermediate directories. The auth.log has this on the matter: sudo: dovelda : TTY=unknown ; PWD=/var/spool/postfix ; USER=root ; COMMAND=/usr/lib/dovecot/deliver -f toni(a)bogus.oeko.net -d dick(a)example.com Using strace on 'deliver', I get this: # su - dovelda $ echo "blubber" |sudo strace /usr/lib/dovecot/deliver -f toni(a)bogus.oeko.net -d dick(a)example.com ... geteuid() = 0 getgid() = 0 setgid(2000) = 0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ setgroups(1, [2000]) = 0 setuid(2100) = 0 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ setuid(0) = -1 EPERM (Operation not permitted) getgid() = 2000 getegid() = 2000 setgid(0) = -1 EPERM (Operation not permitted) close(6) = 0 geteuid() = 2100 geteuid() = 2100 and subsequently, creating the directories fails. The values in the underlined lines above, 2100 and 2000, are from the database entry of the user I want to deliver the email to. My /etc/sudoers has this for dovelda: dovelda ALL=NOPASSWD:/usr/lib/dovecot/deliver dovelda ALL=NOPASSWD:/usr/bin/strace I'm using a Debian/Lenny system with amd64 and this package for Dovecot: # dpkg -l 'dovecot*' Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii dovecot-common 1:1.2.13-1~bpo secure mail server that supports mbox and ma ii dovecot-imapd 1:1.2.13-1~bpo secure IMAP server that supports mbox and ma Kind regards, --Toni++

[Dovecot] Sieve error on Quota full (Dovecot 2.0.3)
by Cassidy Larson 23 Sep '10

23 Sep '10

Just switched my storage boxes to 2.0.3 with Pigeonhole. Noticing for those that have quota fulls, my syslog is getting full of errors from sieve: dovecot: lda(user(a)host.com): Error: sieve: script /data/mail/host.com/user(a)host.com//.dovecot.sieve failed with unsuccessful implicit keep (user logfile /data/mail/host.com/user(a)host.com//.dovecot.sieve.log may reveal additional details) Checking the .dovecot.sieve.log I see: sieve: info: started log at Sep 22 00:38:11. error: msgid=<dovecot-1285137490-378260-0(a)storagebox.host.com>: failed to store into mailbox 'INBOX': Quota exceeded ( mailbox for user is full). Any way to suppress these quota full messages from filling up my logs and .dovecot.sieve.log ? I do like the .dovecot.sieve.log for debugging, but regular quota warnings seems excessive. Thanks, Cassidy
