[Dovecot] best choice of user database file to work with postfix?
by Phil Howard 23 Apr '10

23 Apr '10

I'm setting up a Postfix and Dovecot combination. What I want to do is have a user database that (1) is not running from some engine (so not LDAP or SQL or such) ... and (2) is completely disassociated from system users (e.g. most email users are not in /etc/passwd and most /etc/passwd users are not email users). Ideal would be a one-file solution, which can be managed by text editing or simple command line tools. But what I want is ONE file that both Postfix (for valid recipients) and Dovecot (for user login authentication) can use together. An alternative is some way to get Postfix to go through Dovecot to query for users (at the time of mail arriving on SMTP so it doesn't queue anything that would later be rejected). This is a smallish setup on one server, with probably a max of 50 to 100 users and 50 or so role account mailboxes over the next year or two. Any recommendations?

[Dovecot] Quota monitoring
by Vlamsdoem 23 Apr '10

23 Apr '10

Hello, I would like to monitor users quotas in Dovecot but I don't find a way to do it for every user. Acutally I can log in with user & password to get the users quota but wat I need is a way to monitor the quota of every user with e.g an admin user which would have an acces to the quota of each mailbox. Is there a way to this? Thanks for your help.

[Dovecot] imap-zlib patch to fix runaway imap process
by Mike Abbott 22 Apr '10

22 Apr '10

Here is a patch to fix the problem where an imap process runs away when imap-zlib is in use. The backtrace showed: io_loop_handler_run -> stream_send_io -> client_output -> o_stream_flush -> o_stream_zlib_flush -> o_stream_zlib_send_flush When o_stream_zlib_flush returns 0, stream_send_io reinstates the IO_WRITE event, causing the infinite loop. diff -ur dovecot-2.0.beta4/src/plugins/zlib/ostream-bzlib.c dovecot-2.0.beta4+fix/src/plugins/zlib/ostream-bzlib.c --- dovecot-2.0.beta4/src/plugins/zlib/ostream-bzlib.c 2010-02-12 20:22:07.000000000 -0600 +++ dovecot-2.0.beta4+fix/src/plugins/zlib/ostream-bzlib.c 2010-04-20 19:15:29.000000000 -0500 @@ -122,15 +122,15 @@ static int o_stream_bzlib_flush(struct ostream_private *stream) { struct bzlib_ostream *zstream = (struct bzlib_ostream *)stream; + int ret; if (o_stream_bzlib_send_flush(zstream) < 0) return -1; - if (o_stream_flush(zstream->output) < 0) { + ret = o_stream_flush(zstream->output); + if (ret < 0) zstream_copy_error(zstream); - return -1; - } - return 0; + return ret; } static ssize_t diff -ur dovecot-2.0.beta4/src/plugins/zlib/ostream-zlib.c dovecot-2.0.beta4+fix/src/plugins/zlib/ostream-zlib.c --- dovecot-2.0.beta4/src/plugins/zlib/ostream-zlib.c 2010-02-18 22:01:56.000000000 -0600 +++ dovecot-2.0.beta4+fix/src/plugins/zlib/ostream-zlib.c 2010-04-20 19:15:29.000000000 -0500 @@ -184,15 +184,15 @@ static int o_stream_zlib_flush(struct ostream_private *stream) { struct zlib_ostream *zstream = (struct zlib_ostream *)stream; + int ret; if (o_stream_zlib_send_flush(zstream) < 0) return -1; - if (o_stream_flush(zstream->output) < 0) { + ret = o_stream_flush(zstream->output); + if (ret < 0) zstream_copy_error(zstream); - return -1; - } - return 0; + return ret; } static ssize_t

[Dovecot] Quota Issue
by Peter Fraser 21 Apr '10

21 Apr '10

Hi All I'm using dovecot version 1.2.4_1 and I noticed something strange. I checked the list but so far I haven't found anything that exactly fits my setup. I'm using maildirs and ldap as a backend to authenticate. A user went over quota, realized it and proceeded to delete a lot of email. Even now, after about 15 minutes, the quota indicator is still showing that he is over quota even though the users mailbox size is down by over 200MB. Why isn't Dovecot showing the change, and is there a way around this? Thanks for any help.

[Dovecot] corrupted index cache file, physcial size, in migration to snow leopard
by Norman Packard 21 Apr '10

21 Apr '10

Hi, I am in the middle of migrating a server from Apple's leopard to snow leopard. Having big problems with migrating mail to dovecot. The version is: # dovecotd --version 1.1.17apple0.5 and I use the migration script provide by Apple, /usr/libexec/dovecot/migrate_mail_data.pl The current problems concern migrating imap accounts. The old data typically shows up to mail clients as only partially migrated, with some issues there, like folders change from being listed on the server to being listed locally, but the biggest problem is that many many messages and folders have disappeared from view. But on the server, they seem to be there, in their correctly migrated place. The log files are full of messages like the ones below, which I'm guessing has something to do with the problem. The number of files with this problem is huge. Are there any scripts to rebuild the index cache files with correct physical sizes? Thanks in advance for any help!

by Michael Kliewe 21 Apr '10

21 Apr '10

Hi everybody, is it possible to limit the amount of POP3 connections/logins per 15 minutes? Many hoster do that, but I cannot find a configuration setting for that. I can only limit the amount of concurrent connections per IP, but not connections per time. Michael
