It is still disconnecting with "Connection queue full", although less frequently. Testing with about 315 IMAP connections right now and same config as earlier today, so it should never hit this condition, right? The weird thing is sometimes when I am testing via telnet, my session encounters this condition and disconnects within the first 5 seconds. It does this with and without these patches. Bill

[Dovecot] Sieve plugin - install help - filters ignored
by Brent Hostetler 14 Mar '07

14 Mar '07

Hello, My setup consists of the following: * Freebsd 6.2 system with software installed from ports tree: * Postfix 2.3.8,1 * postfixadmin 2.1.0_7 * mysql 5.0.33 * dovecot-1.0.r25 * dovecot-sieve 1.0.1 * clamav 0.90_3 * SpamAssassin 3.1.8_1 * amavisd-new 2.4.5_1,1 My mail setup is a virtual user setup with all users/domains sharing same UID:GID. Postfix and dovecot get their User information from mysql tables that are administered with postfixadmin. Mail is filtered through clamav and spamassassin using amavisd-new setup as a content filter. All users mail is delivered such as their maildir is /usr/local/vmail/%d/%u using dovecot's lda 'deliver' agent. The system is working fine as configured.. Mail goes where it is supposed to. Trying to get sieve support and unable to get this going. First step is simulating home directories. >From dovecot-mysql.conf ... changed user_query to user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, @home := maildir AS home FROM mailbox WHERE username = '%u' Added the following to a users maildir: .dovecot.sieve require "fileinto"; fileinto "test"; --- Restart all daemons.. Mail still delivers to inbox. Nothing appears in /var/log/maillog or /usr/local/vmail/dovecot-deliver.log that shows anything but the message being delivered to the inbox. HELP! Brent.

[Dovecot] userdb-vpopmail.c bug in rc27
by Gabor HALASZ 14 Mar '07

14 Mar '07

Hi! I discovered a bug in $subject. Next line caused a compilation error: auth_request_log_debug(auth_request, "vpopmail", "lookup user=%s domain=%s", vpop_user, vpop_domain); I think, te correct version is: auth_request_log_debug(request, "vpopmail", "lookup user=%s domain=%s", vpop_user, vpop_domain); -- Gabor HALASZ <halasz.g(a)freemail.hu>

[Dovecot] Variable %h not recognized in userdb_mail (passwd-file)
by Michal Soltys 14 Mar '07

14 Mar '07

As in subject, if you for instance create a simple passwd-file with: test@domain.tld:{plain}pass:20000:10::/home/regular/.test::userdb_mail=maildir:%h/maildir Dovecot (rc23 & 27) will expand %h to empty string, and try to make a directory under / Mar 14 14:25:28 rasengan dovecot: IMAP(test(a)domain.tld): mkdir(/maildir/cur) failed: Permission denied Mar 14 14:25:28 rasengan dovecot: IMAP(test(a)domain.tld): mkdir(/maildir/.Trash/cur) failed: Permission denied ... If tilde is used instead of %h, the expansion works properly. While checking it, I tested other variables (putting aside craziness of using some of them), so summing it up - h,w,i,a,b don't work, all the other ones do. In case %h is not actually intended to work in passwd-files, some wiki examples would have to be adjusted.

[Dovecot] Issue with pop3 & phpList
by Chris Harner 14 Mar '07

14 Mar '07

Hello, all. Dovecot really sparked my interest when I noticed it focused on security. It seems to be a great product thus far. Anyway... I'm new to the mail world (pop3/smtp), and I have a project in which I use a mass mailer known as phpList. If you aren't familiar with it, it has the ability to view and process bounces. Bounces are basically emails that don't quite make it (for the most part). In order for this to work, I must create a pop3 account. I installed Dovecot and now the port is open, which means the service is running. Here is where it gets confusing... When I goto process the bounces, it times out because of the fact that there were too many login attempts. Does dovecot have a default username/password? How do I set up a username and password? Is there a special way to just have the pop3 portion of Dovecot load? I went through the config file and took out some of the #'s like the docs said. Thanks!

Nice :) I've mentioned 'memory' because of the Spanish (is it Spanish? Just guessing) fragment 'espacio de memoria' remembered me to the English word of 'memory', I was wrong here it seems. So forget about memory, it was only my guesswork about your native language :) The lesson here: please translate all messages to English if you want to post to an English mailing list. Otherwise some people (like me) have no chance to understand just guessing ... :) -- - Gábor

It has Dovecot 1.0rc2. I now see there have been 25 rc's since then. (Yikes!) So I guess I should be complaining upstream. I did search the net for several weeks, however, and found no mention of this problem, even in the Dovecot wiki or mailing list archive. So if you say it's fixed, then I'll put something in the wiki to that effect and go badger the Ubuntu guys for an upgrade. :-) Cheers, Tudor.

I think I configured Mailman to drop all text/html MIME parts. Lets see if it works. html -> text translation is also enabled.

[Dovecot] Dovecot for "push email"
by Matthew Sheffield 14 Mar '07

14 Mar '07

Does anyone have experience here using a combination of Dovecot and a Windows or Palm client that supports IMAP IDLE to achieve "push email?" I'm doing some research into how feasible this is for companies and non-profits.
