Hi, I'm in the process of migrating my ISPConfig server (126.96.36.199) to another server. So I've setup the new server, copied all the mail files (vmail), websites (www), databases (mysql) and seems to be working fine. The final step is to change the MX records to point to the new server (I've reduced the TTL of the record already), but I'm sure there will be still emails coming to the old server for a short window of time. So I would like to relay/forward all the email that gets to the old server to the new one. I've looked into Postfix transport, but not sure if it's the way to go. Any advice/direction would be highly appreciated! Thanks!
