[Dovecot] per-user limit?
by Peter Hessler 29 Feb '12

29 Feb '12

I am seeing a problem where users are limited to 6 imap logins total. One of my users has a bunch of phones and computers, and wants them all on at the same time. I'm looking through my configuration, and I cannot see a limit on how many times a single user can connect. He is connecting from different IPs. Any ideas? My logs show the following error when they attempt to auth for a 7th time: dovecot: imap-login: Disconnected (no auth attempts): rip=111.yy.zz.xx, lip=81.209.183.113, TLS $ dovecot -n # 2.0.16: /etc/dovecot/dovecot.conf # OS: OpenBSD 5.1 amd64 ffs auth_mechanisms = plain login base_dir = /var/dovecot/ listen = *, [::] mail_location = maildir:/usr/home/%u/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl passdb { driver = bsdauth } service auth { unix_listener /var/run/dovecot/auth-master { mode = 0600 } unix_listener /var/spool/postfix/private/auth { group = wheel mode = 0660 user = _postfix } user = root } service imap-login { process_limit = 128 process_min_avail = 6 service_count = 1 user = _dovecot } service pop3-login { process_limit = 64 process_min_avail = 6 service_count = 1 user = _dovecot } ssl_cert = </etc/ssl/dovecotcert.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve postmaster_address = postmaster(a)theapt.org } -- We are all in the gutter, but some of us are looking at the stars. -- Oscar Wilde

[Dovecot] Post-login scripting - Trash cleanup
by list＠airstreamcomm.net 29 Feb '12

29 Feb '12

We are considering using the post-login scripting to clear trash older than 90 days from user accounts. has anyone done this, and if so did this cause logins to slow down too much waiting for the trash to purge? One idea was to execute the trash purge script once a day by tracking their logins and seeing that it has already ran that day. Another idea was to call the trash purge script in the background and continue without acknowledging that it has finished to keep logins speedy.

[Dovecot] Master user

Hi, I'd like to have a master user that can read the other users mailboxes. I have only one user who read and write the mail (i.e. I use the static userdb) and I use namespace for public and shared mailboxes. I can authenticate to the server but I am not able to list the mailboxes: > emiliano@dovecot:~$ telnet localhost imap > Trying 127.0.0.1... > Connected to localhost. > Escape character is '^]'. > * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. > 1 login user*master password > 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in > 5 LIST "" * > * LIST (\Unmarked) "."

Hey Timo, Subject says it all... This question is a result of an ongoing discussion on the mozilla enterprise list... Is there a standard/reliable way for an IMAP client to determine that an IMAP server supports server side search (with indexes)? Thanks, -- Best regards, Charles

[Dovecot] LDA alias resolution problems..
by Nick Warr 28 Feb '12

28 Feb '12

I use postfix + dovecot LDA + mysql virtual users and up til friday, everything was working just fine. Dovecot is 2.0.beta6 (3156315704ef) Like I said, up til friday, when I added a vacation entry into postfix (which I have now removed to see if it was the reason) mails to the alias virusalert (which is aliased to me) went through just fine. Now I get these sort of errors from the LDA: Feb 27 11:54:03 cluster2 postfix/pipe[31267]: 866F0A41173: to=<virusalert(a)mobilia.it>, relay=dovecot, delay=357414, delays=357413/0.79/0/0.05, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Fatal: Unknown user ) Other aliases work perfectly, the only difference is that these emails are of local origin, (they're messages from Amavisd) I'm not sure why this has started to be a problem. Can anyone give me an idea where I should start looking? Nick
