SMTP communication problem with the recipient's email server |
|
|
My internal Domain and Public domain use different domain extentions. We are
Dudek.com Publicly and Dudek.int internally. Several mail servers
intermittently reject our email with this meaasage:
There was a SMTP communication problem with the recipient's email server.
Please contact your system administrator. <corp-email.dudek.int #5.5.0
smtp;550 relaying to <username@domain-name.com> prohibited by administrator>
I can see the problem, they think it's coming from Dudek.int and there is no
DNS lookup for that domain. How do I get my Exchange server to send mail as
if it was from Dudek.com as it actually is, so that it matches our public DNS
and these mail servers will see that and accept it. Should I the Default
Virtual SMTP server box and change the FQDN or enter a Masquerade Domain?
Thanks,

Question 2. If I do this will I have to put up a DNS entry for
corp-email.dudek.com or will our current MX record (mail.dudek.com) work?
