I had an issue this morning where internal email was working fine, external emails where being received but receiving external emails weren't getting through. Telnet worked fine to the server from the outside (although if you sent an email it never made it to exchange) so I didn't think it was an ISA server issue with a rule but I restarted both servers just to be sure and when they came up everything worked fine. First question is: Why did this happen? 2nd around here is, what happened to the emails, did they goto la la land? #3 is what can I do about this to reassure people they get their mail? Can an email be sent to 2 different servers at the same time? Or is the backup exchange just for if the main server is down? Let me know what you think, Thanks, Dan Daniel A.
