The MX20 is just a backup MX acting as relay-only function. No mailboxes there. Only one POP3 server (at the end, one A record to point to when user looks for mail) in the primary box-->MX10 > > In order to keep the backup MX from functioning as mailbox server, do you > export the primary Imail registry to the backup box, but don't restore it > to the backup MX's registry until it must be promoted to primary mailbox > server, so the backup Imail server remains are relay-only MX? I export the registry and other useful information from IMAIL folder to a third box. Different from MX10 and MX20 boxes. Just a backup server use for backup purposes. If I finally loose my MX10 box. I setup a brand new one or format the MX10 box and restore the information from the third box. I don't send the backup information to the MX20 box, although I could do that just for redundancy purposes when doing the daily backup... and if necessary I could promote that mx20 box to mx10, but I rather prefer to keep it as a relay box and setup a brand new one (new box or format the mx10) > > > I have schedule my primary Imail server to save the registry and Imail > folder every day via VP-LAN into another box for backup purposes. > > oops, here it's not clear.

This is much more > than "standard backup MX operation -spool and forward-". uhmm if you said so.. I believe you are right. Just a spool and forward operation is not enough for my "soul"..jeje. I feel better if I do daily backups of the registry and parts of the Imail folder in my third box. As a matter of fact I have a lot of redundancy doing backups of the sites we host and the SQL DB we provide to our clients. so.. if somebody asks "what about your backup plans" I can say.. "sure, we have some" and be very specific when necessary.
