Faw (33935) writes "I have looked and asked around but I've found no answer for this. Maybe someone here can give me some advice or recommendation. I have 2 mail servers (main,backup). Only main is visible from the outside, backup is internal. All I want to do is have main receive and deliver the message to the local accounts, but also send the email to the backup server to be processed. I don't want to use rsync (or anything like that), I want the backup server to process the email the same way main does. Does anyone have *any* idea on how to setup something like that? I'm using postfix+dovecot."
