setting quota through IMAP
by Daniel Tröder 22 Jun '15

22 Jun '15

I'd like to set the quota of a user through the IMAP protocol. I use Pythons imaplib: imap.setquota("test1m(a)uni.dtr", "(storage 8192)") ('NO', ['Quota can be changed only by admin.']) So... which user is the "admin" user in a virtual user setting (passwd: PAM, userdb: LDAP)? Greetings Daniel

how do I conceptualize system & virtual users?
by lejeczek 22 Jun '15

22 Jun '15

I guess this would be a common case, I am hoping for some final clarification. a few Linux boxes share ldap (multi-master) backend that PAM/SSSD uses to authenticated users, and these LDAPs are also is used by Samba, users start @ uid 1000. Boxes are in the same both DNS and Samba domains. Do I treat these users as system or virtual users from postfix/dovecot perspective? If it can be a matter of choice then which is better/best? many thanks.

Re: Virtual Mailboxes

The first bonehead maneuver seems to be: location = virtual:/var/mail/%%d/%%n/mdbox/virtual I'm thinking it should be: location = virtual:/var/mail/%%d/%%n/mdbox/mailboxes/virtual But...it didn't seem to make a difference. And if I have the "virtual" folder tree under a location other than "/var/mail/domain/user/mdbox/mailboxes" no names appear - so I think I have the files in the right place.

Virtual Mailboxes

Having some trouble with my first attempt at virtual mailboxes. I've enabled the plugin in 10-mail.conf, added a virtual namespace, and created the dovecot-virtual files in the folders. I see the folder names in the list when I refresh the folders available for subscription - but the folders cannot be subscribed to and I can't view their contents.

Dovecot 2.2.16: disappearing messages, mismatched summaries, duplicated messages, excessive full re-downloads
by David Gessel 20 Jun '15

20 Jun '15

My Dovecot 2.2.16 server is interacting poorly with a variety of mail clients. The symptoms include disappearing messages, mismatched summaries, duplicated messages, and excessive full re-downloads. Dovecot 2.2.16 on FreeBSD 10.1-release r280247M ZFS is interacting suboptimally with various email clients. Output of "dovecot -n" further down. *Client Artifacts* Thunderbird 31.6 Win 7 Ultimate SP1: - messages disappear and reappear with checks somewhat randomly. - Sometimes full re-download of folders is triggered, also seems random - Copies of messages appear, sometimes multiplying with each mail check up to about 5-8 or so of each message. - The summary information in the list pane doesn't match the message headers in the preview pane - quit and restart always cleans it up. - sometimes changing folders cleans it up, but not always - sometimes instigating a manual mail check cleans it up but not always Mulberry 4.08 Win 7 Ultimate SP1: - messages disappear and reappear - full re-scans of entire folders triggered occasionally when changing folders, but not always - message list filled with semi-blank entries (message number, status flags, and dates are listed, but no sender, subject, or body is available). The time stamps do not appear to be correct "date received". - message list fills with duplicates - the last of the set of duplicates, which are not necessarily sequentially numbered, has load-able body text and headers, but the others do not. There may be 3-5 copies, only one of which is the real message. The inbox is sequentially numbered by "message number" (the "natural order of the mailbox") and duplicates have unique numbers. - If there's a deleted message left, the "expunge" button is enabled and this also restores normal mailbox view. - disconnecting and reconnecting usually fixes the issues - changing mailboxes while connected sometimes fixes the issues. Claws 3.10.1 Win 7 Ultimate SP1 - initial load is correct, but once claws tries to sync mail, it locks up and never releases (even after days). Claws is weird like that. Sylpheed 3.4.2 Win 7 Ultimate SP1 - mail list always looks fine, but sometimes clicking a message shows "can't display" in the preview pane - "get messages" restores access to messages. Thunderbird 31.5 Linux Mint 17 Qaina 3.13.0-24-generic - messages disappear and reappear with checks somewhat randomly. - Sometimes full redownload of folders is triggered, also seems random - Copies of messages appear, sometimes multiplying with each mail check - The summary information in the list pane doesn't match the message headers in the preview pane - wrong message total (every other client agrees on 2576 but TB-linux says 3242, perhaps counting dups) Claws 3.9.3 Linux Mint 17 Qaina 3.13.0-24-generic - Occasionally shows "this message can't be displayed" - executing a "get mail" fixes the error K-9 5.004 Android 4.3 - messages appear and then disappear on the next check - message body is occasionally blank (only subject and arrival time appear, no body preview line, clicking on the message shows "no text" *Server artifacts:* dovecot.log shows runs of this error: Apr 15 09:02:37 imap(user(a)domain.com): Warning: Maildir /mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID (old uid=306286, file=1429102024.M826331P1156.host,S=1678,W=1724:2,S) or this error: Apr 15 10:04:00 indexer-worker(user(a)domain.com): Warning: Maildir /mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID (old uid=306803, file=1428785463.M645546P27215.host,S=5389,W=5442:2,S) # grep -c "Expunged message reappeared" dovecot.log.0 8981 The first entry in dovecot.log.0 is at Apr 15 10:00:12, and the last entry at Apr 15 12:00:13; Dovecot is logging 4,490 expunged message reappeared messages per hour.

I tried removing most of my customizations one by one and testing, but the problem has not been improved. I strongly suspect that the index files are getting thrashed or otherwise abused. I have no idea what's triggering whatever event is resulting in the thousands of expunged messages reappearing, but the client artifacts suggest a mismatch between cache or index files and files on disk: UID, keywords, and set date appear as if from cache but the body of the message does not. It seems as if the UID doesn't match a message on disk any more, which soon gets automatically fixed and everything syncs again until something re-triggers - a false expunge perhaps? Or perhaps the transaction log is suffering some sort of ongoing abuse? *dovecot -n* # dovecot -n # 2.2.16: /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.7 # OS: FreeBSD 10.1-RELEASE

I think reason was a damaged Index in ~username/mail/.imap/INBOX/ I removed this folder and immediately errors are gone and Mailbox was readable again. Never noticed this kind of errors for years on 2.1.17, maybe this helps to find a Bug in Code. Thanks, Hajo

hi everybody I've barely started reading on dsync and I wonder.. would you know if it is possible to sync/replicate only specific domain(users)? or it's always the whole lot? many thanks P.
