Dovecot/Pigeonhole Issue (UTC modtime instead of localtime)
by Christoph Gröver 06 Aug '15

06 Aug '15

Hi List, We are using the following setup: Dovecot-2.2.18 Pigeonhole-0.4.8 (for Dovecot-2.2) After the mail is finally delivered via a fileinto by the Sieve filter it gets an updated timestamp (modification time). The server has localtime setup correctly IMO (UTC +0200), but still the delivered mail is setup as being two hours old. I think I found out that the function sieve_file_storage_update_mtime() is the cause of this problem. But perhaps there has to be some kind of setup, that tells pigeonhole to use the 2 hour offset of CEST. I think to reset the mtime by utime(s) is a bit strange. It already gets the correct modtime just by storing it in the filesystem. Last version we used (0.2.5) did not have this poblem. So it must be there for some reason? Perhaps you can enlighten me. Thanks for your time.

Dovecot sieve pigeonhole permission
by Gerhard Wiesinger 05 Aug '15

05 Aug '15

Hello, I'm running dovecot in a classical vmail.vmail setup with pigeonhole and LMTP. Permission worked well in the initial setup but currently (maybe after Fedora 22 update) I'm having the following permission issue: lmtp(root): Error: 7fPZFOL9wFXePQAABcdabc: sieve: binary open: failed to open: open(/etc/dovecot/sieve_after.svbin) failed: Permission denied (euid=9999(vmail) egid=9999(vmail) missing +r perm: /etc/dovecot/sieve_after.svbin, we're not in group 0(root), dir owned by 0:0 mode=0755) lmtp(root): Error: 7fPZFOL9wFXePQAABcdabc: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve_after.svbin.myserver.mydomain.15838.) failed: Permission denied (euid=9999(vmail) egid=9999(vmail) missing +w perm: /etc/dovecot, dir owned by 0:0 mode=0755) lmtp(root): Error: 7fPZFOL9wFXePQAABcdcbc: sieve: The LDA Sieve plugin does not have permission to save global Sieve script binaries; global Sieve scripts like `/etc/dovecot/sieve_after.sieve' need to be pre-compiled using the sievec tool rpm -V dovecot dovecot-pigeonhole doesn't report any permission issues Versions: dovecot-2.2.18-2.fc22.x86_64 dovecot-pigeonhole-2.2.18-2.fc22.x86_64 Relevant config parts: mail_gid = vmail mail_uid = vmail plugin { sieve = ~/.dovecot.sieve sieve_after = /etc/dovecot/sieve_after.sieve sieve_dir = ~/sieve } ls -lad /etc/dovecot/ drwxr-xr-x. 3 root root 4096 Jul 30 18:13 /etc/dovecot/ ls -la /etc/dovecot/*sieve* -rwxr-x--- 1 vmail vmail 288 Aug 8 2014 /etc/dovecot/sieve_after.sieve -rw-r----- 1 root root 355 Jul 30 18:13 /etc/dovecot/sieve_after.svbin What's are the recommended permissions for the files/directories (also for root service startup of dovecot)? Did something change in permissions management? Thanx. Ciao, Gerhard -- http://www.wiesinger.com/

Hi i can send mails without problems in any direction, except when the attachments are bigger than 1 MB. I alway get this message relay=mail.example.net[private/dovecot-lmtp], delay=35155, delays=35155/0.03/0.02/0.09, dsn=4.3.0, status=deferred (host mail.example.net[private/dovecot-lmtp] said: 451 4.3.0 Temporary internal failure (in reply to end of DATA command)) Aug 3 19:34:34 46185 dovecot: lmtp(6477): Disconnect from local: Temporary internal failure (in DATA) postconf message_size_limit message_size_limit = 0 postconf mail_size_limit mailbox_size_limit = 0 i can send big attachments to an extern address but not from intern to intern. Someone said that maybe the tmp directory is the problem so i checked the size. ls -ald /tmp/; df -h /tmp/ drwxrwxrwt 4 root root 80 Aug 3 19:44 /tmp/ Filesystem Size Used Avail Use% Mounted on - 1,0M 4,0K 1020K 1% /tmp root@example:/tmp# is there a connection between lmtp and the size of the tmp directory?

Renaming shared mailbox makes it disappear from sharee
by Andy Csillag 03 Aug '15

03 Aug '15

I've run into an interesting thing. If a mailbox has been shared to a second user (I'll call it the sharee), and there are subfolders on that mailbox, and the sharee renames one of those subfolders, it disappears from view to the sharee. The only way I've been able discover to fix it is to have the sharee create a new subfolder -- then the renamed folder shows up again; in addition to the newly created folder. For example, first(a)example.org shares it's INBOX to second(a)example.org. There's a folder INBOX/thing, which second@ renames to INBOX/renamed (ACLs permitting). second@ can no longer can see INBOX/renamed (or INBOX/thing for that matter), via IMAP's LIST command. But if second@ creates a new folder INBOX/other, INBOX/renamed is now visible. This is very reproducible for me. I also tried it without the imappostlogin bit (in the dovecot -n). Anyone else run into this? No NFS is involved, this is a single machine setup.

Structure of dovecot.index.pvt.log
by Miloslav Hůla 03 Aug '15

03 Aug '15

Hi, we are migrating from Cyrus to Dovecot and I would like to migrate seen flags for shared folder too. We have Dovecot 2.2.13 prepared as: location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n Now I'm looking for 'dovecot.index.pvt.log' syntax to be able migrate Seen flags. All I know is, that index contains messages UID and Seen flag. May I ask you for a link to doc (if it exists) or into a source code? Should I care about 'dovecot.index.pvt.log' timestamps? Thank you, Milo
