RE: POP3 and SMTP server for an ISP

sorry... i am quite new to debian.

I am looking for a mailsystem that can forward incoming mails via
ruleset to another host (on sendmail i user virtusertables). How can
this be done with exim.
you are talking quite a lot about gnu pop3d... what is the deb package
name ??

There are none.

Go figure. :)

Yup. I've been using Exim since way before it was part of Debian. I've
*never* had a problem.

Well, another testimony is that I use Exim on the SMTP gateway machine
for bnl.gov, and it uses an extensive filter to look for 'nasties', 
does the black-list blocking, along with our own long list of unsavory
sites, subjects and content filtering. Nominal traffic is about 1.5-2.0
GB/day, each way. All mail for the site goes through this box. It's
handled up to about 20GB in a single day, and the load on the box never 
went above .10. This is a PIII-500 with 512MB RAM. *Way* overkill for
what it's handling. 

Someday in the near future (6-10 months) we'll be upgrading the WAN
connection from OC-3 to OC-12. It may be a little more loaded at that
point, but I doubt it.
