Lex,

I am trying to identify attachments in incoming mail. For instance, if an incoming mail has an attachment "SAMPLE.PDF", I would like to simply add a header. So, I have the following statement in RULES.MER:

If attachment ExtnPart contains "pdf" AddHeader "SpamCheck: !PDF!" 

The message is not moved / copied in filtering process. But this does not add any header as I want.

Also, the following command

if body contains ".pdf" weight 31 

in content control file SPAMBUS.DAT does not generate the weightage.

What may be the cause?

I am trying to figure out  filter rule / content control command to generally identify attachments. For instance, the following filter rule:

If attachment ExtnPart contains "pdf" AddHeader "X-SpamCheck: !PDF!"   (filter)

if body contains ".jpg" weight 31 (content control command)

do not seem to work. Any help will be much appreciated.

Hi b11, can you give us a bit more info on what you are trying to do and what filter and content control lines are not working as you would expect?

A couple of points about this one

1) I find that I need to include the . in the extention eg:

If attachment ExtnPart contains ".pdf" AddHeader "X-SpamCheck: !PDF!"

to get the filter to work as I expect.

2) this will not add a header if the email message is subsequently moved or copied in your filter rule set.
