Account specific SMTP host names

[chamann]

Hi,

I have just replaced my Exchange 2003 server with Zimbra. The mail migration went well but now I have some serious SMTP aka spam issues. I host multiple domains on the server and I would like to make sure that while sending the Zimbra SMTP MTA identifies itself correctly.

An example:

If the email address is myself@abc.com Zimbra should use mail.abc.com but if the sender is myself@zxy.com it should use mail.zxy.com.

How can I configure that? Right now it sends all mails with the hostname (in my case anduin.athome.local). Result is that my mails are classified as spam (sender name and DNS MX records do not match)

Regards,
Christoph

Welcome to the forums

You will not be able to do that as the server will be identifying itself based on the forward and rDNS entries. The closest you will be able to get is for Postfix to re-write using a header check anduin.athome.local to something else.

Hi,

thanks for the quick reply! How can I do that with Postfix? (sorry, Exchange person speaking ) A quick example would be great!

Cheers,
