Using exim, rather than postfix. The greylistd that was apt-get installed
on my ubuntu seems to have fitted in quite nicely with my exim setup and
had a prebuilt whitelist.

I've noticed some delays and more of the quirk where my home cable
connection is the prefered MX host. Although I haven't done a real
thorough investigation, it seems that more email is going through my
secondary MX.. and ending up in a different account. Something I now need
to tidy up a bit.
Just as well it is a short working week ;-)
