That's a good point.

Depends on the user. Some groups of people tend to use html or both.

The spam phrases were messed up in 2.01. A typo (or a thinko) in one
of the arithmatic expressions.

Depends on the context of the message. Some people will write a lot.
A newsletter could be long. Including lots of log messages or system
details can be long.

Yep. It's going to be fixed in 2.02. (that's what's holding back the

I don't know how easy that is. In the config file it shows that a
perl function is called to test those. Perhaps a perl function needs
to be made for each one?

This is the likeliest cause of your problems with it. If you can
build your own corpus then you can run the GA yourself and get default
scores tailored for your mail usage. One issue the developers face is
coming up with a corpus and scores that work for everyone. For geeks,
any message talking about making money is probably spam. For
management of a company (whose mail admin runs SA), newsletters, etc,
discussing markets and money making are desired, rather than spam.
About the only thing I can suggest for you, if you really want to give
SA another chance, is to customize the scores for your usage.

but a kind word cheers him up.
