[Dovecot] RTFM: Manual pages for Dovecot v2.0
by Pascal Volk 01 Jun '10

01 Jun '10

Hello Dovecot admins. I've started writing manual pages for Dovecot v2.0. I'm sure they are not perfect yet. I'd like to ask you all to read the manual pages. It would be nice to get some ideas/suggestions/improvements. So that that the Dovecot v2.0.0 release could be distributed with /fine manuals/. The manual pages are available at: http://wiki2.dovecot.org/ManPages This is also the intended place for 'discussions' about the man pages.

[Dovecot] Error: file_dotlock_open() failed with file $FILE ENOENT
by Pascal Volk 31 May '10

31 May '10

I've deleted some empty IMAP folders, using Thunderbird. But before deleting them, I had a look into Trash directory on the filesystem: /home/pvo/mdbox/mailboxes/Trash/ ├── dbox-Mails │ ├── dovecot.index │ ├── dovecot.index.backup │ ├── dovecot.index.cache │ └── dovecot.index.log ├── Dev │ └── dbox-Mails │ └── dovecot.index.log ├── S4 │ └── dbox-Mails │ └── dovecot.index.log └── Server4 └── dbox-Mails └── dovecot.index.log (Yeah, looks good, no dbox-GUID file.) After deleting all IMAP folders from Trash I found this lines in the log file: Apr 06 05:44:36 imap(pvo): Error: file_dotlock_open() failed with file /home/pvo/mdbox/mailboxes/Trash/S4/dbox-Mails/dovecot.index.log: No such file or directory Apr 06 05:44:36 imap(pvo): Error: file_dotlock_open() failed with file /home/pvo/mdbox/mailboxes/Trash/S4/dbox-Mails/dovecot.index.log: No such file or directory Regards, Pascal -- The trapper recommends today: fabaceae.1009606(a)localdomain.org

[Dovecot] dovecot-2.0-pigeonhole/ManageSieve: wrong service name
by Pascal Volk 31 May '10

31 May '10

Hi Stephan, ManageSieve uses the wrong™ service name for the authdb lookup. With dovecot-1.2-managesieve the service name was changed from 'managesieve' to 'sieve'. So I altered my table layout in order to make the query "SELECT userid AS "user", password FROM dovecotpassword('%Ln', '%Ld') WHERE %Ls" work again. When I try to login on the sieve port 4190/tcp, I find this in my dovecot.log: auth: Error: pgsql: Query failed, retrying: ERROR: column "managesieve" does not exist auth: Error: LINE 1: ...", password FROM dovecotpassword('user', 'example.org') WHERE managesiev...

[Dovecot] Permanent flags not announced and public mailbox with per-user index
by Julien Danjou 31 May '10

31 May '10

Hi, I've a set of public mailboxes that all users can access. The index is stored per user, so each user can mark the message as read for themselves. This is with dovecot 1.2.10. However, when selecting the mailbox, system flags are not announced as permanent but only as session flags: 3619 SELECT "public.Admin" * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 324 EXISTS * 0 RECENT * OK [UNSEEN 171] First unseen. * OK [UIDVALIDITY 1254326934] UIDs valid * OK [UIDNEXT 1102] Predicted next UID * OK [HIGHESTMODSEQ 1] Highest 3445 OK [READ-ONLY] Select completed. I think (reading the RFC, but I bet you know it better than me) that FLAGS should also been set in PERMANENTFLAGS since they can be permanent. The relevant code seems to be in commands-util.c (dovecot 1.2.11): void client_send_mailbox_flags(struct client *client, bool selecting) { […] if (mailbox_is_readonly(client->mailbox)) { client_send_line(client, "* OK [PERMANENTFLAGS ()] " "Read-only mailbox."); } else { […] } } Even if it's true that the Maildir is read-only, it's still possible to store \Seen permanently. Am I getting things wrong, or is this a bug? If I'm correct, a simple fix MAY be not to send the PERMANENTFLAGS at all since the RFC says: OK [PERMANENTFLAGS (<list of flags>)] A list of message flags that the client can change permanently. If this is missing, the client should assume that all flags can be changed permanently. Thanks, -- Julien Danjou // ᐰ <julien(a)danjou.info> http://julien.danjou.info

[Dovecot] Dovecot 2.0beta4 HG 11189: dovecot-uidvalidity warning with mdbox mailboxes

[Dovecot] Dovecot 2.0.beta5: dovecot-uidlist: Duplicate file entry at line X
by Chris Laif 31 May '10

31 May '10

Hi, I'm using dovecot 2.0.beta5 (IMAP and LMTP+sieve) and I'm getting lots of errors like this: Warning: /data/mail/4567/Maildir/dovecot-uidlist: Duplicate file entry at line 3: 1274182284.M635158P16414.mail,S=767,W=785:2,S (uid 5 -> 16) All data is stored on local disk (ext3, no NFS!). As this is a fresh installation of dovecot I do not know if older versions work better. One user complained about loosing email from inbox but I guess that's probably a user error :) I think that the error might be related to deliveries via LMTP as this (new) functionality has not been tested extensivly (?)

[Dovecot] cur folder e-mails are not shown...

Hi All! I realized that I have only e-mails from last 13 days. I see that I have lots more in the cur folder inside my Maildir folder. The problem is that I cannot see them.

[Dovecot] 1.2.11, mbox, new mail
by Stan Hoeppner 31 May '10

31 May '10

With 1.2.11 and mbox storage, the delay time in pulling new mail headers to the client from imap folders seems to be directly proportional to mailbox size, regardless of the number of new messages. At present, if the mailbox is large, pulling new headers is rather painfully slow. Is this expected behavior? Especially given that the client already has all the "old" mails in the folder cached, and thus wouldn't be asking for them? Is there a setting(s) I can change to optimize/fix this? -- Stan

[Dovecot] strange sieve situation
by Andy Dills 31 May '10

31 May '10

Hi there, I've been working on rolling out the "deliver" service so we can implement sieve. Dovecot 1.2.11, Postfix 2.6.6, FreeBSD 8, installed by ports. Clustered environment, NFS backend. Everything is working great for the most part, I'm using it to sort a copy of my personal email on a test server. However, I noticed two emails were not properly sorted. I had added a rule (using Ingo, nice little piece of software) to redirect the nightly FreeBSD security output emails into a folder "servers". However, nothing had triggered that rule, and the "Maildir/.servers" directory had not yet been created. Then, three of the "security outputs" came in at one time: May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070108.F2F0B7F5D4(a)mail-out04.xecu.net>: failed to store into mailbox 'servers': Mailbox already exists May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070109.D8F5E159913(a)mail-out01.xecu.net>: failed to store into mailbox 'servers': Mailbox already exists May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070109.D8F5E159913(a)mail-out01.xecu.net>: stored mail into mailbox 'INBOX' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: execution of script /mail/var/mail2/xecunet/andytest.xecu.net//.dovecot.sieve failed, but implicit keep was successful May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070110.17A781B53B9(a)mail-out02.xecu.net>: stored mail into mailbox 'servers' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: msgid=<20100529070108.F2F0B7F5D4(a)mail-out04.xecu.net>: stored mail into mailbox 'INBOX' May 29 03:01:48 mg8 dovecot: deliver(andytest(a)xecu.net): sieve: execution of script /mail/var/mail2/xecunet/andytest.xecu.net//.dovecot.sieve failed, but implicit keep was successful That's the order they appeared in my logfile. I'm assuming they were all sent to deliver at the same time, they all thought they needed to make the directory, the one with msgid 20100529070110.17A781B53B9(a)mail-out02.xecu.net was able to make the directory and get delivered, whereas the other two freaked out because they couldn't make the directory they thought needed to be made, and just sent the mail to the inbox. That's a reasonable approach, although I wonder if deliver/sieve could be (or perhaps "has been in 2.0") adjusted to more intelligently handle that edge case. Also, I'm wondering about "dovecot_destination_recipient_limit = 1". I have that set in my main.cf, but I'm not 100% positive it's taking effect. # grep dovecot /usr/local/etc/postfix/main.cf dovecot_destination_recipient_limit = 1 virtual_transport = dovecot # grep dovecot /usr/local/etc/postfix/master.cf dovecot unix - n n - - pipe flags=DRhu user=mailman argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} # postconf | grep dovecot smtpd_sasl_type = dovecot virtual_transport = dovecot # postconf | grep destination_recipient_limit default_destination_recipient_limit = 50 lmtp_destination_recipient_limit = $default_destination_recipient_limit local_destination_recipient_limit = 1 relay_destination_recipient_limit = $default_destination_recipient_limit smtp_destination_recipient_limit = $default_destination_recipient_limit virtual_destination_recipient_limit = $default_destination_recipient_limit Is "dovecot_destination_recipient_limit" being converted into local_ ?
