Hello,

To filter Cyrillic spam, do I need to copy this text into the Keywords Filter window and save it?

((?i)charset=("){0,1}.*((windows-1251)|(koi8-r)|(2022-jp)))
((?i)subject:.*koi8-r)

Is that all? I'm a bit confused about where to place it. Thanks.

Hi Desperado,

your reg ex expression for Koi8r are doing its job! No more cirillic spam in almost a month hard testing.

Thank you!

rudaf,

If a message get through with the new keywords, please contact me by PM. I will want to see the headers and source to see if there is some other thing I can do to improve the regular expression.

...uhm...we are trying as suggested by desperado (thank you, by the way).

Anyway the original question was:

1) we had koi8-r (exaclty as you read it) in keywords.

2) in that way SF filters 90% of cirillic mail with such a keyword in subject as well as in body

Why for the 10% it skips the check?

I don't think it is a reg ex syntax problem, since as i showed above there's no reg ex issue in my first question.

We are testing the desperado's suggestion.

I will report the results.

Regards

rudaf,

Desperado is correct. I myself just realized that the keywords support the use of MSDOS-like style wildcards. As the "?" and "*" are considered wildcards, you can't use them with standard searches. You will thus need to use a RegEx to specify them.

Test failed.

with keyword: "Subject: =?koi8-r?" a few mails pass the filter.

(anyway the major part of filtered mail that maches the keywords has "koi8-r" in the subject. That's exclude the regular skipping of the subject.

here below a mail passed the filter after updating keyword list upon your suggestion
