Dovecot under Linux with mail-extension and case insesitiv
by Sascha 06 Aug '15

06 Aug '15

Hello, i use doevecot 2.2.18 current. My Problem is with email-extension and case sensitiv folders. Example: user+extenstion will be delivered to the user and subfolder extenstion so this is okay. but user+extenstion will not be delivert to the user and exiting subfolder Extenstion so that is not okay. The mail will be also delivered in the subfolder extension. The exiting Folder Extension will not used. Give's a way to tell dovecot, use the extension as a Folder, if a exiting folder with Upper/Lower Cases will be detect and use the right folder to delivery? -- Regards Sascha --- Diese E-Mail wurde von Avast Antivirus-Software auf Viren geprüft. https://www.avast.com/antivirus

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)?

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

Question RE listescape and separators
by Jakob Curdes 30 Jul '15

30 Jul '15

Hello, we just start moving a large number of mailboxes to a new dovecot server with dovecot 2.0.9 (from CentOS) and sdbox as mailbox type. We use imapsync so there is no issue with mailbox type conversion. However, in test runs I noted that some mail folders,e.g. with dots in them, could not be transferred; dovecot says Couldn't create folder [7.8) Personnel] from [7.8) Personnel]: 106 NO Character not allowed in mailbox name: '.' We have the separator "/" defined for our only namespace so the dot should not be an issue!? I tried to use listescape but either the plugin is not loading (how can I verify this?) or it does not escape the dot in the mailbox name. The listescape settings are the defaults: namespace { separator = / (...) } mail_plugins = $mail_plugins listescape plugin { listescape_char = "\\" } What am I doing wrong? How can I make dots in mailboxes possible? Best regards, Jakob Curdes

Hello Sascha, sieve scripts are quite easy, see Steffen's example. I think what you want your script to do is: With any detail part, lowercase it, file message into detail folder, create as necessary. Something like auto-variables in Makfiles, where the rule gets its value from the target, e.g. -- peter

Deafness
by Steffan Cline 29 Jul '15

29 Jul '15

I’ve started in the last day or so having issues where users get a timeout when connecting to dovecot. The iPhone interprets this as an auth issue but re-entering the password makes no change. Outlook will either just not connect to it at all or it gives an error to re-enter the password also with no change. This happens within an hour of a "service dovecot restart". I’m using CentOS 6 with dovecot 2.0.9 from the centos repos. There’s nothing visible in the logs. Suggestions of what to check for? Thanks, Steffan
