You don't need two instances for that. One will do just fine. - Receive email on port 465 and to send that out to the internet. That is handled by the smtps or submissions example in master.cf. No transport map needed. Just remove the '#' from those lines. - Receive email on port 25 from the internet and forward messages for specific destinations? That involves a transport map and relay_domains as described in https://www.postfix.org/STANDARD_CONFIGURATION_README.html#backup Wietse _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
