I remember a while ago you said you had a rule to prevent Chinese spam. I'm now getting stuff from Japan, but redirected through Yahoo.co.uk so I can't use the From domain to bomb it.

What's the test you apply?

Is it coming in with a Subject header that begins with these characters:

=?

We simply just block anything with a subject that begins with those
characters.  I believe they're the begin marker for the encoding of the
Chinese characters or any other multi-byte character set.

Thanks I'll implement that. What odds I don't see one of those for a few weeks so I wait and wonder if its working

Roy Lambert

You'll find a lot of European language will start with that too - people
who write with umlauts etc in the subject. I'd add a few more of the
encoding language digits to be sure.

That said, if you can whitelist on people with your product names, or some
magic word that real users will know, then it wouldn't be a problem.

I was wrong - I've had several and the rule works perfectly - thanks.

This one is for domestic emails rather than business - I get lots of spam to work but no Japanese ones yet

Currently I'm just shoving them into my suspicious folder so I can make sure only the rubbish goes so when I get a few more I'll check if there are more characters I can use.

All suggestions welcome.

I should have mentioned that also - we give preference to anything that has
the word "DBISAM" in it, and let it sail on through.  On a related note, we
also block on a lot of other keywords in the subject like "pill",
"enlargement", etc.....

There's a case on the web where someone objected to the planning
permission of a neighbour, and the council didn't get his objection until
after permission was granted and he emailed without the word "erection" in
the email. Single word filtering can be very dangerous unless you use
weights (I used to sell a spam filter - used DBISAM as it happens) and
customers were always getting caught on single words losing their mail.

Good idea - I'm not sure I could stand a larger Tim......

I saw that one as well. I particularly liked the bit about the council didn't even have the ability to set the keywords themselves it came with the software!

Not sure if I believe them though
