[SAtalk] my procmailrc (with sa-learning of FPs and FNs)

[Duncan Findlay]

I've mentioned from time to time that I'd post my procmailrc to this
list.

Here's how it works... all my mail goes through spamassassin. If it is
a false positive, or false negative, I "bounce" it to daf-ham or
daf-spam (respectively)

My account name on my box is daf. You will want to change this!

My "nice" calls may not be necessary depending on your system.

I use maildirs, you may not. In that case, get rid of the /
