    Posted: 29 July 2003 at 3:58pm

I have a number of emails that show up in my mail client with a series of .....  (periods) plus a comma instead of readable text.  When I export the email as plain text it appears as a series of ????? (question marks) and a comma in notepad. Must be a font issue.

I have added the following RegEx statements to the filter, but some still got through:

((..,){3,8})
((??,){3,8})

Have you seen these emails? It's always overeas sourced mail.  I would prefer not to block countries. Any ideas on refining rhe removal of this overseas spam with RegEx is appreciated.

In addition can anyone help me with RegEx to block the upper character set like this?

从四月一日起,下例地区加收E。B。S。

东非 --20/--40

南太平洋 --50/--100

伊­克战争爆发,船公司考虑征收新的战争附加费。

从四月一日起,运价几乎全线上涨。具体情况另告。

Thanks,

Dwight

PS: Dan, your RegEx filters are super.  You get the RegEx salute!

The previous RegEx did not render correctly in the forum preceeding each period or comma was a slash \.

Thanks

Dwight,

Not an answer, but a comment. I, personally don't want anything with a foriegn char set either BUT, as an ISP, we can't block them.  2 things though .... perhaps a future release "Wish List" would include a way to "expose" the Char Set setting and then it could be used as a trigger and 2nd ... LogSat is working on a "DNA Fingerprint" method of detecting spam and that may help in that area.
