Dovecot listens on different interfaces for different services

Question

I'm just setting up Dovecot 2 and I wanted to have it listen on port 993 for imaps on all interfaces and listen on port 143 for normal imap only on the loopback interface.

That way I'd have less publicly open ports and can still use a non-tls connection for a webmail client running on the same server.

I can change the listening ports here:

Service imap-login {
  inet_listener imap {
    address = localhost
    #port = 143
  }
  inet_listener imaps {
    #port = 993
    #ssl = yes
  }}

and with listen = *, :: I can change the interface, but not separately for different ports. the listen command does not work inside the inet_listener block.

Ok, I actually found the answer in some commit log for dovecot while typing the question. The relevant command is address = [...] not listen.

So it now looks like this:

service imap-login {
  inet_listener imap {
    address = localhost
    #port = 143
  }
  inet_listener imaps {
    #port = 993
    #ssl = yes
  }}
