    Hello! I've followed the debian postfix/virtual email hosting tutorial & keep getting these "no good user" SMTP errors whenever I try to send emails to my virtual domains from any non-local hosts.

    I'm imagining that this is an rDNS entry issue, but is there a way to solve this without having a unique IP for every domain I want to provide email for?

    Are you sure that the MX records for your domains point to the correct server? You can check with
    dig mx

    Let's see... The server's name is, all of whose email addresses are working. But I'd like the virtual domains I'm hosting to work as well. Here's the digs:

    All pretty normal looking, eh?

    An MX record must point to an A record, not to an IP address.
