Exchange 2000 won't deliver mail (SMTP - Unable to bind to the destination server in DNS)
Posted on 2003-11-06
Okay, Here is the lowdown...
Exch 2000 isn't letting any emails out... we can get emails in and we can send locally. I can look in the SMTP queue and see all of them just sitting there, with the error Unable to bind to the destination server in DNS. I have tried using a few different DNS servers, with no luck.
The network set up -- Three Servers (Exchange, File Server, SQL Server) sitting behind an ISA Server. I can telnet to port 25 on external servers, so i know that i can get out.
Not sure what to do...
