Plesk 12.5 Ubuntu 14.04
Postfix
HELO domain.tld works most of the time. (also that's our reverse DNS entry)
But we got a specific receiving server that only accepts emails from us if we send HELO mail.domain.tld (so our MX record). even though that resolves to the same IP (I only managed to configure that manually in the postifx/master.cf)
Is that actually correct behavior? (RFC: http://www.freesoft.org/CIE/RFC/1123/90.htm) If so I'd really need a Plesk setting for this - otherwise my manual change gets overwritten every time I change something witht the mail settings.
(Or do you think HELO with IP woud work also?)
