If the latter, then Wietse's answer covers it. I'm actually testing three scenarios: 1. Mail relaying through my cluster of servers by others. 2. Mail submission by MUAs. 3. IMAP access by MUAs. All of them should load balances correctly across replica SMTP and IMAP servers. DNS round-robin seems to be good enough for this and avoids complex load balancing proxies. _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
