We have an exchange 5.5 SP 3 server on NT 4.0 behind an ISA / SMTP fire wall server on windows 2003. AOL will ot accept our e=mail because even though we have a valid and reverse DNS traceable address on our firewall, we still show the name of the file server and the internal domain name of the exchange server in the header. How can we strip out the internal header information of our outbound e-mails so it that the only reverse DNS is on our external domain?
Can you do it in Exhange 5.5? SMTP server? ISA? IIS?
Help!
