Hi there, hopefully this can be easy: as I have $myhostname other than virtual domain name, when server relays my v.d. mails, it uses $myhostname and so sometimes I receive a refusal like this: "550 Reverse DNS lookup failed for host"; how should I make server use my virtual domain's name when relaying from virtual domain's address, so that lookup succeeds? Any other thing comes in mind what could likely cause such problem?
