[Mailman-Developers] sendmail

[Dan Mick]

I've come to the conclusion that

1) postfix takes the message no matter what synchronously and queues it,
which eliminates a lot of the wait problems, and

2) yes, the validation step can be short-circuited with things like
"mynetworks" and "relaydomains" and that set of stuff, and I think
the "default" is to allow locally-originated mail to go out without
sender-DNS lookups.
