I am a new subscriber to SpamCop's e-mail filtering
service - already I love it!
Question: I see that I can set up a blacklist to
block e-mail by listing a sender's adress; is
there a way to refuse the acceptance of e-mail
according to the content of the subject line?
What you have displayed in the link below is subjects which contain 8
bit ascii chars
The reason I ask is because I get a lot of e-mail

I use SpamPal which has a user configurable regex plugin which contains
a line:

SUBJECT: 220.0 {([\x80-\xff].*){6,}} [SUBJ_FULL_OF_8BITS Subject is
full of 8-bit characters]

which means that regex would assign a value of 220.0 [of 500 for spam]
for the appearance of 8 bit chars and I could tune that value up or
down -- or I could tune up or down the 'breaking point' for spam value.

I'm not experienced with SC mail's filter system, but my understanding
is that you can't 'reconfigure' the SA SpamAssassin filter rules, you
can only adjust what level of value you want to recognize as spam. SA
has a lot of different kinds of rules to cover issues like these, but I
don't think you can independently configure them. The SA rules which SC
uses and their values are the same for all SC mail users. I think.
(note: I have all the DNS Blacklist options selected,
and SpamAssassin level set to 5)
It would be nice to be able to configure filters
that would disallow delivery of such e-mail.
eg: if subject contains Æ, do not receive.
If there is a way to do this, please tell me how.
Also, is there a way to deny acceptance of e-mail
according to country of origin?
Yes, but I think there was a problem with that filter or list recently.
Maybe it is fixed now.

This discussion group is about general questions about spamcop; there
is another ng about questions about the SC mail service, and some of the
people who support mail questions prefer to support those questions in
the webforum.

I'll post this reply to both groups and make followups to spamcop.mail.

I have OE rules set to throw away mail with those 8-bit characters.

OE's message rule sez "where subject contains words"

What do you put in the words field?
