Since you believe this isn't a spammer, you don't need any of the process hogs
like antivirus or spamassassin, or even need mailscanner because the sender
already knows what his content is ;-) and should be able to achieve the goal
with one of these. With quad core Xeons very common right now, it should be
fairly easy if it has a big enough pipe to the internet, and you tune things
like timeouts and retries to run later or not at all.
Being an opt-out list, you could probably just dump the retries, and just
shotgun the messages out to where they fall.
I see just another direct marketer trying to compete for MY bandwidth.
Someday, people will be smart enough to not buy things marketed this way ...
never mind, won't happen. Look at the people that still fall for 419 scams.
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
