Hello Markus,

thanks for your help.

If the email has an attachment with an extension of ".doc" or the type 
is "application/msword", the list may be increased in the future, I want 
to set the custom header.

Why am I doing this? The second filter only applies if found a header 
set by amavis according to clamd dlp scan. Clamd fails to detect some 
word (.doc) files that the second filter handles correctly.

Your solution seems pretty easy and I will check it out right now. It 
could be a useful workaround for my problem.

i'm still also interested in the custom check because It will be more 

Thanks a lot for your answer.
