Mail Filtering or rewriting

2001-08-14 Thread Md. Sifat Ullah Patwary

Hi all!

Recently we are facing a problem of mail bombing from
some MS Win9x customer. Its due to a email worm. It
sends a virus file attached with. extensions are
*.pif, *.lnk etc.

I was looking for any patch which will help me to scan
this attached files and do the needful. Is there any?

Secondly, some clients are sending a mail with 1000 cc
or bcc to my local users. Is there any tools to stop
this junk mails?

Thanks in advance.

Sifat

yes, of course, use qmail-scanner. It has userdefinable attechment 
filters, and can operate an commercial virus scanner for mime 
attachments. you have to apply the qmailqueue patch, and define a 
QMAILQUEUE variable in your smtp startup script. 
qmail-scanner is very nice, i use it myself to protect those windooze 
computers in my network.

yes, of course. Most probably the tarpitting patch from qmail.org will 
help you in this issue
