How to filter mail that have the extension *.exe, ...etc...

[Chan Choth PUTH]

Dear Sir or Madam:

I would like to configure my Linux server to filter all mails sending from my users that have the files such as *.bat, *.exe, *.com, *.scr, *.pif, *.wav that my users sending to another user in the whole world via my domain (mail server) because I think that these files may contain viruses. Would you mind telling me the steps of doing it? Thank you so much for your assistance.

Regards,

Choth

Hi,
There is an excellent perl tool called sanitizer. Download it from
http://mailtools.anomy.net
It can meet your requirements.

Dear U.SivaKumar,

Thank you so much for your answer. If I use sanitizer to sanitize mails, I think that just only for the incoming mail, but what about outgoing mail? I would like to filter all the outgoing and incoming mails. Would you mind if I asked you what steps could I do? Thank you so much for your assistance.

Regards,

Hi,
You can also use amavis, which is A Mail Anti VIrus Scanner. In fact, it is working with anti virus software, and scan attachment. But you need to purchase an anti virus software (there are also free anti virus software). See :
www.amavis.org, and
www.openantivirus.org
Many requisite to make it works, but for me it's OK !
