[Dovecot] Dovecot problem after last Debian sid update
by Paul Scott 25 Feb '09

25 Feb '09

Hi All, After upgrading dovecot for sid Thunderbird no longer displays the contents of any emails I have had a working IMAP setup for as much as a year even though I don't understand dovecot configuration well enough to know how I got it to go in the first place. Here is the output of dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: ~/Maildir auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd TIA for any clues as what to do next.

[Dovecot] OT: Fixing Messages To Be RFC 2822 Compliant
by Neil 25 Feb '09

25 Feb '09

So....apparently I have some messages which are not RFC compliant sitting in my mailboxes (mostly older ones), and I have some software which is refusing to handle such messages. 1. Does anyone know of a nice way to verify that all my messages are compliant/find those that aren't? (I suppose I could use the existing failing software, but I was hoping for something a little more robust...) 2. Does anyone know of any tools that will do The Right Thing as far as fixing these messages are concerned? Googling didn't turn up much for me, but maybe I wasn't hitting the right terms ("RFC message repair", "fix email message", etc.). Thanks.

[Dovecot] Rename INDEX
by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi I think there is a technical reason for this, but I am not sure. My IMAP client shows a folder called INDEX. This is my maildir. I wonder if it is possible to change the name of this folder to something else? -- Daniel

[Dovecot] Read-Only IMAP
by Neil 25 Feb '09

25 Feb '09

Inspired by the "Dovecot as a email storage system" thread... Is there a way to instruct Dovecot go into read-only mode for an account, or a mailbox? Could I maybe fake it by setting perms on the maildir directory to 440?

[Dovecot] dovecot1.2 segfault

I've tried 2 builds of dovecot, based on a amd64 rebuild of the experimental package on http://xi.rename-it.nl/debian/ I've tried to include as much useful info as possible, sorry if I've missed out anything of use.

[Dovecot] Dovecot as a email storage system
by Roderick A. Anderson 24 Feb '09

24 Feb '09

I was thinking about all the old email I have and don't want to get rid of and how much space it is taking on my mail server. The idea came to me to install Dovecot on a server at home then I could drop mail into I want to save. It doesn't need to receive mail except what that is moved to it. Anyone see problems with doing this? Thanks, Rod --

[Dovecot] email stuck in outbox
by barnaby cockcroft 24 Feb '09

24 Feb '09

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users. We haven't ruled out a layer 2 issue but nor have we found one.... If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated. Dovecot version(s) 1.19 & 0.99.11 Configuration from 1.19: # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release 4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd

[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

[Dovecot] "dovecot-uidlist: Duplicate file entry at line" error
by Dovecot List 24 Feb '09

24 Feb '09

This is with respect to an error that I am facing in dovecot. The error is that is seen in logs is "Feb 23 00:04:46 mailblade1 dovecot: IMAP(USERNAME): /indexes/USERNAME/.INBOX/dovecot-uidlist: Duplicate file entry at line 7: 1234776125.M559298P3988.s2o.qlc.co.in,S=13111,W=13470:2, (uid 94277 -> 97805)" This error is seen for multiple users. Once this error occurs for a user, the user downloads mails all over again in POP3. Please help! And let us know what can be done.
