[maildropl] skip checking inside attachments

[Gaurav P. <gau...@di...>]

Hi 

I have sent question before without luck.. sorry for sending it again
but I really need answer of this.. Sam, can u help..
-----------
I am using maildrop with qmail. Everything works like charm but I have 1
problem. I have a rule that searches body of message and checks if it
contains any spam related keywords that I have blocked in my rules file.
The problem is that it also goes and checks inside the
attachment(including binary files). Due to this the load on server gets
very high and there is delay in delivering mail. What I want is that it
should not go and check inside the attachment for the pattern..
What I could do is to allow the multipart/mixed type in the beginning of
my rules only but there are many spams that are multipart/mixed types.
This rule will allow all those mails.
I would like to know a method to skip checking attachment while checking
rest of the body at the same time.

Thanks
Gaurav
