Multiuser attachment storage (mail_attachment_dir)
by megaone＠yandex.ru 06 Jun '17

06 Jun '17

Was trying to set up attachment storage, but folders are receiving permission only for current user, so if another user is receiving a mail with same attachment he is getting permission denied error on reading hash file. Is it possible to setup global attachment storage to work with all users, at least in domain? mail_access_groups won't help, as folders are given 0 group permission. Umask and setfacl won't help either.

Two domains - same user names filter
by Sandbox 06 Jun '17

06 Jun '17

Hi, I have two LDAP domains, which has some equal users, eg: abc(a)domain1.com abc(a)domain2.com I sat up this config: domain1 users maildirs are stored in /home/vmail/username domain2 users maildirs are stored in /home/vmail/domain2/username This works fine except one thing: i cant set up the ldap query to choose the correct maildir if the user names are equal. Is it possible to use a user_filter which will choose the correct maildir and user/domain from the email address? My current ldap.conf for domain1: hosts = ldap.domain1.com base = ou=People,dc=domain1,dc=com ldap_version = 3 user_attrs = uid=user user_filter = (uid=%n) pass_attrs = uid=user,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 and for domain2: hosts = ldap.domain2.com base = ou=People,dc=domain2,dc=com ldap_version = 3 user_attrs = \ =mail=maildir:/home/vmail/%{ldap:departmentNumber)/%n/Maildir user_filter = (uid=%n) pass_attrs = uid=%n,userPassword=password pass_filter = (uid=%n) default_pass_scheme = MD5 Thanks, Robert

vnd.dovecot.pipe in sieve: what user....
by Larry Rosenman 06 Jun '17

06 Jun '17

I have a site-wide bayes database, that currently gets populated by scripts running as a user that is also the user that Exim uses to call spamd. When a script is running from the vnd.dovecot.pipe call, what user is it running as? Would a setuid script work? -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: larryrtx(a)gmail.com US Mail: 17716 Limpia Crk, Round Rock, TX 78664-7281

Better back up what you have before trying anything. Joseph Tam <jtam.home(a)gmail.com>

corrupted indexes rebuilding over and over
by micah 05 Jun '17

05 Jun '17

Hi, On saturday one of our dovecot machines had an OOPS, and we had to powercycle it. When it came up, it did a filesystem fsck (ext4) and fixed a couple things, but nothing in lost+found. Now, about 50 users have a problem where their indexes are corrupted. Dovecot tries to fix them, but for some reason it is failing. The users are seeing their mails duplicated and they cannot delete mails. I can see in the logs dovecot detecting this and trying to rebuild operations during delivery and imap login, but its repeating over and over and over. For one user, I've seen more than 4k lines in the logs about this. If i try to do doveadm force-resync -u username INBOX I get this: doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: Inconsistency in map index (3494,32332 != 3494,383536) doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: rebuilding indexes doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index doveadm(nuffsaid): Warning: mdbox /n/nuffsaid/mdbox/storage: Inconsistency in map index (3494,32332 != 3494,384024) doveadm(nuffsaid): Warning: fscking index file /srv/dovecot_indexes/n/nuffsaid/storage/dovecot.map.index but then if i do it again, I get the same thing, over and over and over (the numbers change a little). This is dovecot 2.2.27 with mdbox format.... what can I do to fix this? Its driving users mad, and they keep going over quota as their space fills. thanks! micah

Possible RENAME bug
by Gabriele Bulfon 05 Jun '17

05 Jun '17

Hello, I'm having some trouble working on a webapp managing the imap tree on Dovecot. The same doesn't happen on other imap servers (e.g. Cyrus). Looks like if I receive shared folders from another user, and try to rename a folder in it, the rename command returns "ok", then if you list the new folder name, it isn't there. Looks like you've lost all the original folder because if you try listing the parent folder, you don't have nor the original nor the new name, even trying to logout/disconnect and reconnect/login. Luckily nothing is lost actually, if you try to create a new folder on the parent folder, and then list the parent folder, you get both the newly created one and the renamed one also appears magically! Here is the IMAP trace to reproduce: *** ON ACCOUN RECEIVING SHARED FOLDER *** PREPARE A FOLDER IN SHARED TREE WITH JUST ONE CHILD "aaaa" *** THEN RENAME aaaa FOLDER TO bbbb *** AFTER "OK Rename" FOLDER IS NOT PRESENT IN LIST A3 LIST "" Shared/gabriele.prova(a)sonicle.com/Junk/aaaa * LIST (\HasNoChildren) "/" Shared/gabriele.prova(a)sonicle.com/Junk/aaaa A3 OK List completed.

NOTHING IS LOST. Is there anything I can do to force "bbbb" to reappear without having to create a new folder? Any idea?
