Topic: continuous "Please try again later" messages ...
We are trying to send one simple email to a USER@nokia.com server. (mx1.nokia.com)
But the mail server is constantly sending "Please try again later (in reply to end of DATA command))"
What could be the reason? Should I ask their webmaster to whitelist our domain?
