Line 60 of the Server file needs to be set to your local IP (unless you
modify the code to look at the machines address (the copy I found first in
my delving is the plain vanilla version but I do recall making the change
so the pseudo server was more portable.
The messages file needs to contain a series of mail messages in rmail
format. AntiSpam needs to be set to download/check against the IP rather
than a normal mailbox. (You can add it in to the normal AS mailbox
definitions, or in my case just ran AS on a different machine)
(reminder to self - this is in Internet.netdev.Aspam_add)
Regex - I seem to have a copy of stuff that Kade Hansson was working on too
(Dev.AS_Stuff.OtherVersions.Kade) and what I recognise as an early version
of my efforts Dev.AS_Stuff.OtherVersions.UserTest_Regex
I *know* there is a more developed version. Must be on one of the other
machines. Searching...
(Meanwhile - the grammar check compiles OK, needs riscosifying then see if
it is useful in that form)
