Sorry for the does not make sense post, I will elaborate.
I set up an email server on a Mac mini(named fusion). Since Apple decided to quit the server business, I purchased an additional mini(named SSD) with plan to use SSD system as email server with Fusion system as hardware backup. After a year of operation, the SSD system became extremely sluggish(sometimes 12 hours to receive mail, sometimes never).
Following Apple Care's suggestion, I built the email server from scratch on the Fusion system then exported users from SSD system and imported into Fusion system. Next, I copied /lib/server/mail/data from SSD system and pasted into Fusion system. I am told that if the IDs line up correctly, I will have achieved my goal of having all existing email on a built from scratch email server.
I attempted to simply move my ethernet cable from SSD system to Fusion system to verify mail was valid, but ran into connection problems. The SSD system has a SSL certificate installed. If I ask for a SSL certificate for the Fusion system, the one on the SSD system will be cancelled.
In a normal read/write mail process, the mail client will send a message to a DNS server where the domain name gets translated to the server's IP Address, setting up communication between client and server. Since I can create a client at the same IP address as the server, I was hoping for some how write the client's data directly into the server's message received port....just to verify that the mail I copied did line up with the correct user IDs.
Thanks for any ideas,
Don
