multiple imap servers for high availability
Hello, We run imap for our domain at our lan. I'd like to set up a backup mirror that has imap storage always duplicated. Then using something like heartbeat to share the imapd IP address . Could someone point me to documents , if any , that give ideas on how to set up the mirror? best regards, Rob
Re: how to run dovecot imap on separate server from postfix?
OK I got delivery from postfix to lmtp working , by changing from unix_listener to inet_listener . Reindl wrote "don't open the port for any other machine as the postfix server" I see that is important.. I assume that just a firewall setting? Or does the 'address' line in inet_listener lmtp have something to do with it?

Re: how to run dovecot imap on separate server from postfix?
I'm trying to figure out the exact line to put to /etc/postfix/main.cf for local lmtp deliver we use: mailbox_transport = *lmtp:unix:private/dovecot-lmtp* for remote it is supposed to be:* lmtp:host:port* yet at the remote lmtp does not use ports. UNIX domain sockets are used instead: netstat --listening --programs| grep lmtp unix 2 [ ACC ] STREAM LISTENING 8457 3696/dovecot /var/run/dovecot/lmtp unix 2 [ ACC ] STREAM LISTENING 7998 3834/master private/lmtp unix 2 [ ACC ] STREAM LISTENING 7630 3696/dovecot /var/spool/postfix/private/dovecot-lmtp Is there a different setting for lmtp using 'domain sockets' ?

Re: how to run dovecot imap on separate server from postfix?
Hello Reindl, thank you for the response. I want to make sure that the postfix delivery does not give up trying to get the email delivered when the lmtp host is not reachable. I do not just want to assume that the default settings are correct for us. Are there postfix or other settings which can be checked and adjusted?

how to run dovecot imap on separate server from postfix?
Hello we are using version 2.2.13 on debian. currently imap runs on the same system as postfix , spamassassin and other mail related software. I'd like to move dovecot imapd and mail storage to its own system. I've search google and wiki and could not see how to do so. could someone please point me in the direction to that done? I like reading documentation.. here is more info on our set up: postfix: # grep dovecot /etc/postfix/* /etc/postfix/main.cf:mailbox_transport = lmtp:unix:private/dovecot-lmtp /etc/postfix/main.cf:smtpd_sasl_type = dovecot kind regards Rob Fantini
Re: [Dovecot] 2.0.5 Error: Timeout waiting for handshake from auth server.
check your mail log, if you get this: Authentication service cannot retrieve authentication info then it could be related to this bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=566844 if you do have that issue let me know, and I'll look up our notes to post a work around.

Re: [Dovecot] anti-spam+anti-malware suggestions
check postgrey , it works great with postfix . http://www.debuntu.org/postfix-and-postgrey-a-proactive-approach-to-spam-filtering postgrey should I think be used in addition to the other suggestions. since we started using postgrey the amount of work done by our other anti-spam software, spamassassin , was cut at least 90% .
