Mail delivered to www.domainname only...

[twgray]

When I send mail to anyone on my server, it has to be addressed to name@www.domainname instead of name@domainname. If I address it to name@domainname, Postfix thinks I am trying to relay mail...

If I change my mx record to domainname from www.domainname, Postfix thinks I am trying to relay mail.

Does anyone know how to fix this?

Please add a co-domain domain.com to the website www.domain.com in ispconfig.

Thanks, that did the trick.
