Re: [Solved] How to configure dovecot imap to listen on multiple ports?
I'm running Debian Wheezy with Dovecot version 2.1.7. The following works for
me:
- /etc/dovecot/local.conf ---
service imap-login {
inet_listener imap {
#port = 143
}
inet_listener imaps {
port = 7993
ssl = yes
}
inet_listener imaps2 {
port = 993
ssl = yes
}
# Number of connections to handle before starting a new process. Typically
# the only useful values are 0 (unlimited) or 1. 1 is more secure, but 0
# is faster.
#service_count = 1
# Number of processes to always keep waiting for more connections.
#process_min_avail = 0
# If you set service_count=0, you probably need to grow this.
#vsz_limit = $default_vsz_limit
}
- /etc/dovecot/local.conf ---
Thanks for all the help!

OK, project for today: Give this a try…

Thanks! Gedalya and Jochen! I hadn’t realized I could do that with iptables. I’ll read-up on the documentation.

I have a dovecot imap server inside a NAT/firewall.
The NAT translates calls to port 30143 and 30993 (not the real ports, but just
for example) coming from outside to 143 and 993 inside. So machines outside
the NAT that want to talk to the server use ports 30xxx and machines inside the
NAT use the regular ports.
Which works fine for machines that are at fixed locations. But a laptop that’s
sometimes inside, sometimes outside doesn’t have a fixed port to connect to.
For those cases, I’d like the dovecot server to recognize the outside ports on
the inside.

Can I have multiple “service” clauses for the same service? Each with a
different port?
Or multiple “inet_listener imap”/“inet_listener imaps” clauses?
Or should I have something like this?
port = 143,30143
How to configure dovecot imap to listen on multiple ports?
I need my dovecot imap server to listen on ports 143, 993, and also 30143 and 30993. What syntax do I use in (I presume) the /etc/dovecot/conf.d/10-master.conf file to do this? Thanks! Rick

Hmmm... This doesn't work for me. My dovecot.conf has
protocol imap {
# rbt - use conventional port for imap -- only used on local net
listen = *:143
# rbt - use modified port for imaps -- for those logging in from afar
ssl_listen = *:7993
ssl_listen = *:993
}
I get:
# invoke-rc.d dovecot restart
Restarting IMAP/POP3 mail server: dovecot
Fatal: ssl_listen: Can't resolve address *:7993 , *: Name or service
not known
failed!
This is on a Debian Lenny system. The version of Dovecot installed is
"1:1.0.15-2.3+lenny1"
Do I need a later version?

I sent this a while ago, but got no answers. Maybe it got lost?
Thanks!
