I am trying to send email from webserver to my iredmail server via phpmail. The hostname of webserver is random non-FQDN name.
the mail log shows, "domain not found 450". I believe it is because random.randomhost.net is not being resolved.
How can I allow emails from this random host to get through without changing its hostname.
I'll truly appreciate some help here.
