I am having trouble preventing Qmail from doing open relaying without
stopping mail service entirely. This is on a system that runs Listserv(R)
from the L-Soft Corporation. When I put the system's name (and aliases) in
a rcpthosts file, open relaying stops. The problem is that no one can send
e-mail to any account on this system. Qmail says that the sending system
is not allowed to relay. I do not understand this. In sendmail, I can stop
third party relaying without totally disabaling mail functionality on the
system, but I can't figure out how to do this with qmail. The Qmail FAQ
file was unclear on this subject, which is why I am asking here.
