I've setup an Exim4 / MailScanner (ClamAV+Mcafee) / SpamAssassin running on
debian woody at Linguistics.  The server works great, and I *strongly*
encourage you to stick with Exim, as it's *great* to work with it's
transport and router filters.

I can't explicitely work on the project, but I'd be happy to help with any
questions you might have, or provide any example config files from our setup.

We run 2 Exim4 processes on the box.  One "incoming" process, one "outgoing"
process.  MailScanner sits in between these two processes and is the only
way that they can exchange messages.  The idea is that an email comes into
the incoming process, and it accepts / rejects it.  If it accepts, it dumps
it into the waiting queue which MailScanner checks every 60 seconds or so.
Once MailScanner picks it up, it scans it for viruses using ClamAV (updated
twice daily) and then hands it off to the outgoing exim process, which will
either relay it to the outside world, or deliver it to the user's mailbox.
Local delivery is handled by procmail, which first sends the message through
the spamd process for site-wide spam filtering, retaining user preferences.

Everything from the user perspective is configured through a web based
interface which stores all settings in a MySQL database.  exim4 even allowed
me to easily move the ~/.forward file into SQL.

I haven't heard about greylisting.  Any links?
