[Dovecot] Howto disable imap listener in dovecot 2.0
by Erik Logtenberg 11 Mar '10

11 Mar '10

Hi, How do I disable the imap listener in dovecot 2.0-beta-3? I only want to enable the imaps listener. In previous dovecot versions I could specify: prototols = imaps But in dovecot 2.0 this is no longer possible (imap and imaps are now both enabled with "protocols = imap"). I already made ssl a requirement with: ssl = required This is in the global section. I commented out the imap listener in master.conf, but "dovecot -a" still shows the config for the imap listener, so I suppose it's default configuration. Can I explicitly tell dovecot to not open an imap listener, but only an imaps listener? Kind regards, Erik.

[Dovecot] Limit login attempts per connection?
by Tony Nelson 10 Mar '10

10 Mar '10

Dovecot allows a large number of login attempts per connection. I'd like to reduce that number to, say, 1, and let my firewall keep the ducks at bay, but I can't find anything in /etc/dovecot.conf or by googling. How do I do it? Do I need to patch the source? dovecot-1.1.10-1.x86_64 on CentOS 5.4 -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@georgeanelson.com> ' <http://www.georgeanelson.com/>

[Dovecot] Mailing list's prefix
by Timo Sirainen 10 Mar '10

Do you think I'd break a lot of people's filters if I removed the prefix? :) Anyone strongly for/against removing it? It seems kind of annoying to me whenever I happen to think about it.

[Dovecot] Cannot create auth-master file
by Greg Frith 09 Mar '10

09 Mar '10

Hi all, I'm trying to get postfix and dovecot working nicely together to process and store mail for both local (system) on one domain and virtual users and a few different domains. I've got postfix up and running quite nicely, but am having a few problems with Dovecot. Every time postfix tried to delivery a message to a virtual user using dovecot I get an error like the following in /var/log/mail.log: Mar 8 21:53:58 rhy postfix/pipe[6616]: 89C94846E: to=<gregf(a)gregsfamily.com>, orig_to=<greg(a)gregsfamily.com>, relay=dovecot, delay=8795, delays=8794/0.01/0/0.61, dsn=4.3.0, status=deferred (temporary failure) At the same instant, in my dovecot log I'll get this error: deliver(gregf(a)gregsfamily.com): 2010-03-08 21:53:58 Error: Can't connect to auth server at /var/run/dovecot/auth-master: Connection refused So, I'm guessing that this is a permissions issue (somewhere) and that the dovecot process is not able to create the file /var/run/dovecot/auth-master. The permissions on this folder are as follows: gregf@rhy:/etc/dovecot$ ls -al /var/run/dovecot/ total 0 drwxr-xr-x 3 root root 100 2010-03-08 21:44 . drwxr-xr-x 15 root root 660 2010-03-08 22:00 .. srw------- 1 vmail root 0 2010-03-08 21:43 auth-master srwxrwxrwx 1 root root 0 2010-03-08 21:43 dict-server drwxr-x--- 2 root dovecot 60 2010-03-08 21:44 login I've searched around for hours, found several threads describing similar issues, but no solutions that have worked for me. If anyone is able to give me any pointers or suggestions I would be most grateful. My dovecot configuration is: gregf@rhy:/etc/dovecot$ sudo dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-18-generic x86_64 Ubuntu 9.04 ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps pop3s imap pop3 login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%u mail_debug: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 auth default: mechanisms: plain login user: vmail debug: yes debug_passwords: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail :wq G

[Dovecot] Using MySQL For Mailboxes?
by Carlos Mennens 09 Mar '10

09 Mar '10

I have always seen some people indicate they use MySQL for mailboxes in Postfix and I wondered how difficult something like this would be? I have 300 users on my company Postfix server right now. I am just using Postfix, Dovecot (IMAP4 only), & Roundcube (Webmail). I have MySQL loaded on the machine that runs Postfix but only to manage the database for Roundcube. Do you think that 300+ users is recommended for a MySQL database for mailboxes? Secondly, how difficult is it to configure this? Right now everyone user has a home directory and a mailbox in their private home folder. Is it hard to configure Postfix & Dovecot to use MySQL mailboxes? Just looking for some suggestions since I couldn't find a log of info via Google. *PS* I was told that Dovecot doesn't support MySQL mailboxes. I think it does. Am I wrong? http://howtoforge.com/forums/showthread.php?p=221396#post221396
