I couldn't agree more. I have bogofilter dealing with incoming mail to Kmail,
and it's doing a good job. No false positives, and all the spam ends up in
the trash. I do get a few unsures, but not many. Now and again I look through
the trash to see what bogofilter has put there as spam, but I'm so sick at
seeing the "get-a bigga-dick" stuff that I'm not even going to view the trash
any more.
If anyone that I know sends me mail with a dodgy subject line/content/etc,
then it's hard cheese. It'll go to the trash care of bogofilter.
I got so annoyed the other day, that for the first time in some months I sent
all the spam that bogofilter had put in the trash to spamcop. There were
about 80 spams, and for only one did spamcop say that the ISP concerned was
going to stop spamming, and you have to take that with a pinch of salt. How
serious were they?
I could go ranting on and on, but would be a total waste of time. It appears
that spam will exist while the Internet exists, and we have to deal with it
as end users. Enough said.
Nigel.
