I'm running Centros 4.x with asterisk, with webmin installed. I'm looking for a spam/virus filter that I can install/maintain with webmin that scans incoming mail from my ISP.

For instance:

Setup the virus/spam filter:

1. with ISP pop3/smtp settings
2. Point my local machines to the linux server to grab mail after the linux box has scanned/filted email.

3. Linux box then sends the mail to the local machines

The one's I've found so far for Webmin only are geared towards setting up your domain email server and scan for that, and not an ISP.

One's I've looked at so far are:

Squid Proxy Server
Sendmail Configuration
SpamAssassin Mail Filter
Procmail Mail Filter
QMail Configuration
Postfix Configuration

RAE Internet MPP Panel (using this for virus scan).

Any help would be appreciated.

try using spamassasin for spam, and clamav for av. both are generally well integrated into whatever MTA you use, so your MTA will go.. "sideways" to each service before passing the mail out the bottom.

You really shouldn't live your life by webmin though.. yuck.
