[Dovecot] 1.0a1 Coredumps / errors when moving multiple
by Gregory Bond 05 Sep '05

05 Sep '05

I've just tried upgrading 1.0t51 to 1.0a1 and it has been........ difficult. I've been getting logs of Sig11s and other errors, and have trouble tracking them down. Main problem seems to be with moving / copying messages. One at a time works (mostly), multiple will coredump the imap process (not yet managed to get a proper core out though...) I'm using imap & Maildir, maildir on NFS & Indexes on UFS, Solaris 8. Server is postfix / procmail (delivering pre-sorted into various Maildir folders) and Dovecot 1.0a1. Client is thunderbird on OS/X. If I turn off mbox_copy_with_hardlinks, then instead of a coredump I get a hang and an error message: > IMAP(gnb): Maildir /home/gnb/Maildir sync: UID inserted in the middle > of mailbox (3871 > 3870, file = 1125740849.23189_0.lenford:2,Saa) This is after I've removed all the cache/index files and even all the dovecot-uid files.... I'm back on 1.0t51 for now, but could have another crack at this if there are any hints.

[Dovecot] Dovecot logging
by Black Vette 05 Sep '05

05 Sep '05

Fedora Core 4 dovecot-0.99.14-4.fc4 I'm trying to diagnose some mail issues. I do not believe Dovecot is the problem. If I could see the Dovecot logs, it might be helpful in resolving my issue. In /etc/dovecot.conf I have tried to set the following: log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log I have 'touch /var/log/dovecot.log'. When I try to restart dovecot 'service dovecot restart', it fails and I'm not able to see the reason why it is failing. Where am I going wrong getting this working? Also, are there various debug levels? I saw 'debug' mentioned on the list, but I was unable to see anything about it in the config file. Thanks, Mike __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Re: [Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by Paul Vatta 05 Sep '05

Hi Chris, We migrated to Dovecot from Qpopper/UW-IMAP in July. We previously looked at altering the Dovecot code, client-side duplicate email cleanup utilities (for Eudora), and enforcing "download-then-delete from the server" prior to the migration. We got around the "downloading of previously downloaded emails" problem by moving all previously downloaded emails to a new folder called "ConvertedMail" during the conversion process from mbox (Qpopper) to maildir. This assumes you're going to maildir though. The benefit in this is that the POP client only retrieves email from th inbox folder, and after conversion, this will mean only new emails. If the POP client's previous download of older email dissappeared (for whatever reason), a Web Mail client accessing the mailstore via IMAP would allow access to the ConvertedMail folder. Regards, Paul

[Dovecot] login: Missing Protocol from server name 'imap'
by Phil Bettinson 04 Sep '05

04 Sep '05

Hello All (possibly again) I did send a messge earlier, but it may have been eaten by the mail system. I've now managed to get dovecot started, and I'm now getting "Missing protocol from server name 'imap'" This is somewhat confusing. Does it mean that I have somewhere called my server imap? or is it talking about it missing a protocol called imap? if it's meant to be "missing protocol imap definition" or somesuch, I have filled that out, but can't for the life of me figure out what the error message is actually trying to tell me! I'm running dovecot alpha1 on RedHat as3. I have the feeling I've been staring at the problem for too long, and somone will just say "have you tried this!", but it's worth a shot. Thanks in advance Phil

[Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by grant beattie 04 Sep '05

04 Sep '05

hi all, I am hoping to convert a 350K user qpopper installation using mbox to dovecot and maildir (pop3 only). many of the users "leave mail on server", and qpopper's UIDL format isn't (yet) supported by dovecot. since the UIDLs have been written by qpoppper to the existing mbox files (and will be preserved when the mboxes are converted to maildir) it would be possible to do this seamlessly if dovecot could read the UIDLs from the messages and populate the index files as needed. is anything like this already possible? it doesn't matter what UIDLs new messages get, since they would never have been downloaded by the user via qpopper. any ideas would be appreciated. grant.

[Dovecot] Purge / Delete Problem using IMAP
by A Ve 03 Sep '05

03 Sep '05

Hi, I am using dovecot 0.99.14 RPM on a Fedore Core 4 Server. Everything was running fine for weeks (IMAP), and 2 days ago I was not able to delete/purge any Mail in INBOX. I am using Outlook 2003 as an IMAP-Client. I tried to delete/purge the Inbox with other mail-clients (Mozilla Thunderbird, Mulberry) too, same effect: I can read mail, I can copy them by drag-n-drop to a local Client-Folder (eg: Outlook) , but I can delete them. Strange enough, the mails are marked as read, but when I login again, all Mail are marked as new/unread ! When I log to the node, and start mutt (which is using the spool-file /var/spool/mail/username), then I am able to read-n-delete all Mails... The File Permisson of the File: 755, Owner: Username, Group: Mail. Did I miss something ? How can this stop working from one day to another ? I seems to me, like the INBOX is not writable to me ... From the UNIX Side, it is ... :-/ Any Comment/Feedback would be helpfull. This is really strange. Regards, AVE.

[Dovecot] string expansion *in* dovecot config?
by OpenMacNews 03 Sep '05

03 Sep '05

hi all, is it possible to define/use 'MACROS' (string expansion, ala Exim) in dovecot's config file? specifically, e.g. -- rather than: login_executable = /some/crazy/path/to/dovecot/libexec/dovecot/imap-login i'd LIKE to do something like MY_PATH = /some/crazy/path/to login_executable = MY_PATH/dovecot/libexec/dovecot/imap-login i'm reading the wiki docs, and it's just not obvious to me ... thanks! richard

[Dovecot] Weird internaldate behavior with 1.0-test80 and mbox folder
by Jon Roma 03 Sep '05

03 Sep '05

Has anyone else encountered weird date behavior with mbox-style folders? I am nearly ready to bite the bullet and convert my UW imap hierarchy (which is in mbx format) to Dovecot. In so doing, I need to convert each UW-specific mbx-format mailboxes to the more portable mbox format, which Dovecot can read. (This is done with the 'mbxcvt' utility that's part of UW.) I am then planning to copy those mbox-format folders into a staging area in a directory I've defined to Dovecot as a mbox-format namespace. The plan was then to use my normal GUI to reorganize my old data and copy it into proper maildir folders into Dovecot's default namespace. Since I'm naturally paranoid, I did a dry run of a couple folders first and discovered a rather strange anomaly -- all the mail in the converted folder is displayed by Dovecot with a timestamp exactly 200 minutes (3 hours 20 minutes) into the future! Investigating this via telneting to the respective IMAP ports shows that UW imapd shows the correct timestamp both in the original mbx-format folder and the converted mbox-format folder -- so it appears that Dovecot is skewing the time. This doesn't look like a timezone issue since 200 minutes ahead from CST6CDT would be a pretty strange timezone -- not even Newfoundland has this odd a TZ value! :) (For the curious, Newfoundland is a Canadian province whose time zone is TZ=NST3:30NDT, therefore being a half-hour "off" from the rest of North America.) I have distilled this into a degenerate case of a single folder with a single message and can reproduce. As mentioned, I am running 1.0-test80. My platform is AIX 5.1. I created the test by sending a message to myself using date | mail -s "Test at $(date)" roma(a)uiuc.edu and using my MUA (Mulberry) to file it into the test folder, which defaults to mbx format in UW's namespace. Here's what UW shows when I select/fetch the "original" message: * namespace * NAMESPACE (("" "/")("#mhinbox" NIL)("#mh/" "/")) (("~" "/")) (("#shared/" "/")("#ftp/" "/")("#news." ".")("#public/" "/")) * OK NAMESPACE completed * select "~/Test" * 1 EXISTS * 0 RECENT * OK [UIDVALIDITY 1124811965] UID validity status * OK [UIDNEXT 3] Predicted next UID * FLAGS (\Answered \Flagged \Deleted \Draft \Seen) * OK [PERMANENTFLAGS (\* \Answered \Flagged \Deleted \Draft \Seen)] Permanent flags * OK [READ-WRITE] SELECT completed * fetch 1 internaldate * 1 FETCH (INTERNALDATE "23-Aug-2005 11:16:37 -0500") * OK FETCH completed * fetch 1 envelope * 1 FETCH (ENVELOPE ("Tue, 23 Aug 2005 11:16:30 -0500" "Test at Tue Aug 23 11:16:29 CDT 2005" (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) ((NIL NIL "roma" "uiuc.edu")) NIL NIL NIL "<200508231616.j7NGGUrc022618(a)zippy.cso.uiuc.edu>")) * OK FETCH completed Next I use the UW 'mbxcvt' to convert the folder, leaving it in mbox format in a different folder (~/Test-mbox) -- still in UW's namespace.

Notice the "internaldate" response. Dovecot reports the correct time zone, but the internaldate value is 200 minutes ahead of what it should be!!!
