It could also prevent the catch-22 situation I wrote about earlier whereby a filesystem out-of-space condition will result in a user not being able get themselves out of that situation, since a mailbox operation (like a delete and expunge) will not be able to create a lockfile. Having quotas handled by the IMAP/LDA will allow extra room to handle this impasse. Disabling dotlock or using dotlock_try locking method are some other workarounds.

[Dovecot] Timeout leak in get quota
by Danilo 10 Oct '11

10 Oct '11

Hello! I wrote perl script for read current quota usage, it works but when I run the program I receive a warning in Dovecot log: 2011-09-29 14:45:30 doveadm(guest(a)testmail.com): Warning: Timeout leak: 0x7f14800ad970 This is the script: =============================== #!/usr/bin/perl use strict; use Socket; use IO::Handle; socket(TSOCK, PF_UNIX, SOCK_STREAM,0); connect(TSOCK, sockaddr_un("/var/run/dovecot/doveadm-server")) or print("ERROR!"); print "VERSION\tdoveadm-server\t1\t0\n"; print "\tguest\(a)testmail.com\tquota get\n"; print "=" x 20 . "\n"; if (defined(my $messg = <TSOCK>)) { print $messg; print TSOCK "VERSION\tdoveadm-server\t1\t0\n"; TSOCK->flush; print TSOCK "\tguest\(a)testmail.com\tquota get\n"; TSOCK->flush; $messg = <TSOCK>; print $messg; $messg = <TSOCK>; print $messg; close TSOCK; } ============================= I hope someone could help me to fix the warning. Thanks in advance, Dany

[Dovecot] Filesystem quotas
by Steve Fatula 10 Oct '11

10 Oct '11

I am wondering if I really need to use dovecot quota functions or not. Assume for the moment, that, each system user has a quota defined using Linux quotas, and that the Maildir is within their quota limited directory. So, any mail (or files created by the user etc) that would exceed the quota obviously can't be created. In such an environment, is there any advantage to implementing the same quota already defined in the filesystem via dovecot? Or, can I just make things simpler and ignore dovecot quotas? Assuming I keep the index and control files out of the quota limited directories. I presume if exceeding filesystem quota, the mail will not be delivered of course. If using lmtp, I presume it stays in the queue to retry later for some period of time. Steve

[Dovecot] lazy expunge namespaces
by Micah Anderson 07 Oct '11

07 Oct '11

I turned on lazy_expunge and configured a namespace following the wiki[0] instructions for mdbox configuration: namespace { inbox = yes location = prefix = separator = . } namespace { hidden = yes inbox = no list = no location = prefix = INBOX. separator = . } namespace { location = mdbox:~/mdbox:MAILBOXDIR=expunged prefix = EXPUNGED. separator = . } This created an EXPUNGED mailbox in my client (thunderbird), which was greyed out. When I deleted things, they got put in the EXPUNGED mailbox, as expected, but I could not access them to try and "restore" them. The server would say that the mailbox did not exist. micah 0. http://wiki2.dovecot.org/Plugins/Lazyexpunge --

[Dovecot] doveadm mailbox subscribe wildcard
by Micah Anderson 07 Oct '11

07 Oct '11

Hi, I noticed that wildcards work like the following, as described in the man page: # doveadm mailbox list -s -u bob dovecot* dovecot dovecot/pigeonhole dovecot/pigeonhole/2.0 however, wildcard subscriptions don't work: # doveadm mailbox subscribe -u bob dovecot* # doveadm mailbox list -s -u bob dovecot* dovecot dovecot* dovecot/pigeonhole dovecot/pigeonhole/2.0 It seems I subscribed the non-existant mailbox called 'dovecot*' -- is there a better way to handle this? thanks! micah --

[Dovecot] I'm the ONLY user that can get mail
by Ed Hochman 06 Oct '11

06 Oct '11

Hi, I'm stumped. I can access the postfix server to read my mail. BUT I'm the only user that can. Everyone else get rejected. Here's the syslog entry for another user: ...dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<jmarino>, method=PLAIN, rip=192.168.0.51, lip=192.168.0.189 And here's an entry for me: ...dovecot: pop3-login: Login: user=<ed>, method=PLAIN, rip=192.168.0.51, lip=192.168.0.189 So ONLY I am able to get my mail. And this is consistent. The other users and passwords are valid. I've re-set them just to be sure. I suspect it's a rights issue but I've checked the rights for all /var/mail files and they're all the same except the owner of the file is the actual owner. I also checked all the rights for the files in /etc/dovecot. They all look OK and they all have root/root for the owner and user. Since I installed the system and did all the editing of the configuration files it's possible, but unlikely, that I'm the owner or group of some key file. I've looked for that but found nothing suspicious. Is it possible I may have given myself root access? I don't see how. My UID is 1000. Does the fact I'm the first user (per my UID) make a difference? I would think not. So I'm stumped. I don't have a clue as to where to look or what to do next. Any thoughts will be greatly appreciated. This is Dovecot 1.2.15 on Ubuntu 11.04. A new/clean install. Plaintext passwords are allowed. Here's dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.38-11-generic i686 Ubuntu 11.04 protocols: pop3 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/pop3-login mail_privileged_group: mail mbox_write_locks: fcntl dotlock mail_executable: /usr/lib/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/modules/pop3 auth default: passdb: driver: passwd passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd Thanks

[Dovecot] Only using LMTP-delivery, where should domain & user aliases be configured, Dovecot or MTA conf?
by mephistopheles＠operamail.com 06 Oct '11

06 Oct '11

I have my MTA (Postfix) check Dovecot2 LMTP for existing users. No other delivery is done; this is a virtual/LMTP-only setup. I define known users in a Dovecot passwd-file, specified in conf.d/10-auth.conf passdb { args = ... username_format=%n /stor01/vmail/auth.d/%d/passwd e.g., vi /stor01/vmail/auth.d/mx1.domain1.com/passwd myuser:{scheme}####:... mail to: myuser(a)mx1.domain1.com is correctly auth'd and stored. I want two things to happen: (1) all mail to existing-users "@domain1.com" gets re-routed to "@mx1.domain1.com", i.e., map: myuser(a)domain1.com -> myuser(a)mx1.domain1.com and is accepted/not-rejected ONLY if 'myuser' is defined as a user in mx1.domain1.com/passwd and, (2) specific 'user' aliasing/remapping within a given domain, i.e. map: whatever(a)mx1.domain1.com -> myuser(a)mx1.domain1.com as long as 'myuser' is a defined user in mx1.domain1.com In these cases, where should I assign domain & mail aliases, Dovecot or the MTA's conf ?
