Ok, I'm not sure if
this is a vpopmail specific question or just a qmail specific question, but I
figured you guys could help me out.
I'm in the process
of setting up a web hosting company that will provide free email accounts (via
qmail). The only problem is, I cannot send email through my server without
being listed in list of valid domains to send through my mail server. What
should I do? This is going to need to allow people to send from any
domain, but I don't want to open up a ton of security holes by setting up an
open relay server. Any advice will be very appreciated,
thanks.
