Dear, all. I have a few questions regarding how to clone/duplicate/copy an incoming/outgoing email message so that the same email got to 2 of my servers.
newserver.mynetwork.com (with Postfix and local IMAP server) -- incoming/outgoing emails arrive at this server first zimbra.mynetwork.com (with Postfix and local IMAP server) -- the _same_ incoming/outgoing emails need to be here also Currently I have a zimbra server running Postfix as its MTA and I want to keep it running as a backup/redundant to a newer server that I am going to install. This new server also runs Postfix as its MTA so all incoming and outgoing emails should go through this new server first. I would like to know of ways to clone all emails so that both servers would have the same copy of incoming/outgoing email messages. I have the same set of users on both server through openldap directory. I read the mailing list and saw suggestions of using virtual alias: u...@example.com u...@host1.example.com, u...@host2.example.com but I would like to have more information on how to do this. I also found some others suggested to use regex to handle that but these suggestions might not be what I need for my situations. Thanks you for any suggestions.
