Hi. I have version 1.1.11 working fine with multiple servers. When I upgrade to 1.2.4 or 1.2.5 I keep getting an error 'can't create auth listener' (address in use)

I have two ip addresses (lets call them 1.0.0.1 and 1.0.0.2). Each ip address has it's own certificate and set of servers with custom ports. I don't know how the configuration is supposed to work and it was a lot of google and trial and error to get it working.

My configuration file is pretty basic so maybe someone can point out where I'm going wrong. I stripped out the few comments and unrelated settings.

#listen = * disable_plaintext_auth = no ssl_ca_file = myca.crt protocol lda { postmaster_address = postmaster@example.com } server a1 { protocols = pop3 ssl_cert_file = a1.crt ssl_key_file = a1.key

listen = 1.0.0.2:110 1.0.0.2:111

auth default {
  mechanisms = plain
  passdb pam {
  }
  userdb passwd {

}}} server a2 { protocols = pop3s ssl_cert_file = a1.crt ssl_key_file = a1.key listen = 1.0.0.2:995 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} server n1 { protocols = pop3 ssl_cert_file = n1.crt ssl_key_file = n1.key listen = 127.0.0.1:110 127.0.0.1:111 1.0.0.1:110 1.0.0.1:111 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} server n2 { protocols = pop3s ssl_cert_file = n1.crt ssl_key_file = n1.key listen = 127.0.0.1:995 1.0.0.1:995 auth default { mechanisms = plain passdb pam { } userdb passwd { }}} ...and repeat for imap, imaps

Thanks, Sean
