My imgate server is the main MX ... I have imail setup as a secondary (but blocked at the firewall). If the imgate is going to be down for a while, I can unblock the imail server at the firewall and still get mail with changing DNS settings or waiting for the DNS to populate.
Since I've done this setup the number of hits to the blocked imail server is interesting ... I see suspect hits (large number of tries) going to the imail server in the firewall log. Also I've seen AOL and MSN try the secondary MX before going to the primary MX (this was found after users complaining about email from those services being delayed). May be I'm not seeing the big picture ... or my setup caused this issue ... I'm just reporting what I've seen. It seams ... that some SPAM programs send to the secondary MX or all MX's for a given domain. Christopher Checca Packard Transport, Inc.
