It is an acceptable loss. It is a required loss, no matter what antispam
rules, antivirus routines, you are _ALWAYS_ going to loose email. If you
want to do a Hotmail like Scheme with a Junk-Email Folder (which is what it
sounds like) that's fine. Seems like a vanity thing, i saw a few sysadmins
drop all spam to a user named spam and let the whole system read the spam.
Seemed highly sily.

_I_ have a Sun UltraSparc 5 running at 366Mhz with 128meg of ram. so CPU
usage is a VERY big issue. I'm sorry that i dont run linux with a Pentium
4 2.0Ghz But my Server is not that, and CPU usage is a very big issue.
I have users that when the anti-spam rules were not there, they would
recieve 500+messages a day of pure unsolicited spam (that's what spam is of
course).
Now they recieve about 5 messages a day of spam, the system is alot happier
since the actual load is lower then it has been in months.
BodyChecks are hard, and headerchecks are worse. There is no perfect
solution for SPAM, the problem is with SPAM is that you have a 'SPAMMER'
who try's to make the mail look as legit as possible, then there are those
who dont care and use some open-relay and send 4,000 messages out at once.
The problem isnt neccesarily the SPAM it's the Administrators that are not
at the console updating sendmail/postfix/qmail so it stops relaying.
No one should have to worry about SPAM, Truthfully one could almost say we
should sue the company's they refer us to. Because obviously they're
getting paid to spam, so why not recouperate our costs from the beneficiary
of the SPAM.
But that's for another discussion.
