Topic: Different EHLO based on domain?
Today I have found out I have a problem with my main server. People trying to send mail to someone else get rejected with a bounce message:
Client host rejected: Rule #1 Please use your ISP's SMTP server to send
I think this might be because of the fact that my smtp always send EHLO greeting with the main hostname (eg, mx2.xxx.com).
Is there any chance to configure the server to send different EHLO greetings when sending mail, depending from the user's domain?
For example, if user firstname.lastname@example.org, and email@example.com try to send email through my smtp, then make my smtp send different greetings based on the sender's domain?
