It is difficult.

what you might be able to do is to configure multiple inet_listeners and then use CoS setup with multiple passdb:s. 

something like:

service imap-login {
  inet_listener imap {
    port = 143
  }
  inet_listener imap2 {
    port = 144
  }
}

and then in first passdb fetch configuration variables:


passdb {
  driver = passwd-file
  args = username_format=port_%{lport} /etc/dovecot/extrasettings.passwd
  result_failure = continue
  result_internalfail = continue
  result_success = continue
}
passdb {
	….
}

and in second passdb {} you can use %{passdb:variables} that you set in the first passdb. Probably can’t set driver = %{passdb:driver} tough..

maybe with setup like this you can achieve what you want.
