Some external emails were being bounced back and i was looking at this link below. http://technet.microsoft.com/en-us/library/aa997324(EXCHG.65).aspx Just wondering what would be the FQDN to enter in the smtp ‘s property - Delivery-advanced. ( from the example above) Should I enter Internet MX record’s FQDN instead of servername.mycompany.local Thanks

Enter the external FQDN of the server that matches its external ip

And that hopefully matches the name on the certificate :)Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Good thing he's using 2003! :p

Thanks for the reply. "matches the name on the certificate?" Is it the "Issued to:" part of the SSL certificate? It is Secure.<mydomain.com> Where as the FQDN I ented is myserver.mydomain.com These two are not matching? Is that the reason some of the external mails are going to the bad mail? Thanks
