[Dovecot] open-folder limit
by T. Horsnell 19 Oct '06

19 Oct '06

Is there a way to limit the number of folders a user can have open simultaneously? I seem to remember a config option which would only permit one imap process per user, and would share this between his folders, but I cant find anything relevant in the docs now. Am I talking nonsense here? I'm new to Dovecot. Cheers, Terry.

[Dovecot] Urgent - Inconsistent Inboxes
by Jakob Curdes 19 Oct '06

19 Oct '06

Hi, An urgent problem that I have : runninng dc 0.99.14 w mbox on local ext3 , nothing special, no nfs, nothing. For this machine we have a backup server rsyncing everything over. Now the main server went down and we started DC on the backup machine some day ago. Everything went well, besides one problem : people complained about missing mails that they had seen beforehand. When looking in the inbox, they were all there. After recreating the imap account (outlook express) or deleting the cache file (thunderbird .msf files) everything was well. But you can't really recreate all accounts after switching to the backup machine every time.... today we went back to the main server and in advance I deleted all .imap.index files hoping that they might have been the eventual cause of the problem, but no, same thing happens again. It now seems to me that this is a pure client issue, but nevertheless two questions : a) who knows a way to tell the client (OE or TB in this case) to disregard all local information and get everything fresh from the server ? b) Can this behavior be influenced from the server side? I know I'm behind with 0.99.14 but up to now there was no problem and "never change a running system". If upgrading could help, I would do it immediately. Any hints welcome, especially fast ones as tomorrow morning I have to get the clients running. Yours, Jakob Curdes

[Dovecot] Assertion failure with Dovecot 1.0rc10
by David Schweikert 19 Oct '06

19 Oct '06

Hi, I am seeing the following (with Dovecot 1.0 rc10): Oct 18 07:35:58 dovecot: IMAP(user): UIDs broken with partial sync in mbox file /var/mail/user Oct 18 07:35:58 dovecot: IMAP(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (15314 > 9604, seq=5, idx_msgs=224) Oct 18 07:35:59 dovecot: IMAP(user): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Oct 18 07:37:42 dovecot: IMAP(user): mbox sync: UID inserted in the middle of mailbox /var/mail/user (15314 > 9604, seq=5, idx_msgs=224) Any idea of what this could be? The user is reporting that he is seeing multiple times the same mails and that the new flag is not being unset after he reads a mail.

[Dovecot] LDAP Username Change
by Todd Johnson 19 Oct '06

19 Oct '06

I have a virtual setup using LDAP where the a user has an email address at 2 domain names. The want the mail kept separate but want to use the same password. I use the mail attribute and insert both email addresses. This works perfectly with deliver but opens the wrong Inbox when I IMAP. Is there a way to disable this in the conf file? host dovecot: auth(default): auth(jeff@idom.net,::ffff:127.0.0.1): username changed jeff(a)idom.net -> jeff(a)jdom.net

[Dovecot] Logging authentication failures?
by dri 19 Oct '06

19 Oct '06

I use a script that watches log files looking for failed ssh login attempts and adds firewall rules when there are enough login failures within a certain amount of time. I would like to apply this to Dovecot to automatically firewall attackers trying to brute-force an IMAP account. Is there a way to make Dovecot log authentication failures (I'm running 1.0.rc10)? In other words, can I configure Dovecot to put something in the log the instant "NO Authentication failed" is sent to the IMAP user? With "auth_verbose = yes" I can see individual authentication mechanisms fail, but I have multiple passdb sections so a failure in one mechanism doesn't mean a complete login failure. Thus, configuring the script to watch for individual mechanism failures may result in the firewalling of legitimate users. Thanks for any info!

[Dovecot] Proxy not working using passwd-file
by Clayton Epp 18 Oct '06

18 Oct '06

I've been having problems setting up my proxy using dovecot. I'm using the passwd-file for authentication as well as the regular unix passwd file. Can someone provide me with a complete example of how this should be done, I'm finding that the documentation on http://wiki.dovecot.org/AuthSpecials is sparse on the details. Please do not assume anything as I am new to both Dovecot as well as Linux (FC5).

[Dovecot] Dovecot-compatible web-based sieve configurator
by Koen Vermeer 18 Oct '06

18 Oct '06

Hi, I've set up dovecot with postfix and I'm using the dovecot LDA. It seems that sieve works, but I'm not that good at writing sieve scripts and I'd like to install something more user-friendly anyway. So: Does anyone know of a web-based sieve configurator that works with the dovecot implementation? I haven't been able to find one yet... Koen

[Dovecot] trash plugin causes crashes in quota plugin?
by Mike Horwath 18 Oct '06

18 Oct '06

I just lost my scrollback - so I'll have to recreate it the issue. Using both 1.0r7 and 1.0r10 on FreeBSD 6.1-STABLE. For the: mail_plugins = quota imap_quota that works fine (using maildir for quota plugin) But... mail_plugins = quota imap_quota trash will cause the quota plugin to die at line 156 of quota.c: root->v.deinit(root); I haven't dug through the code enough to find the actual area for this piece of code to add some debugging. Once I can generate a new traceback, I'll drop another email. -- Mike Horwath drechsau(a)iphouse.net ipHouse - Welcome home!
