JPNerd sniped myself by trying to use PostfixAdmin from @mwl Run Your Own Mail Server, but the version in Ubuntu is from ages ago and the debian packaging mechanism seems to have been unmaintained for a number of years so I forked the upstream and hacked it to minimally work on my machine.
Mosen@daedalus @mwl I remember running postfix at a small biz with greylisting and I thought it was the best anti spam ever. Long lost to the ubiquity of office 365 though. Sad that nobody even maintains the packages
