Bearing in mind that I'm fairly new to all things Linux.... I have a total of 10 mail servers for which I need to provide a higher level of email protection. 9 of them are hosted on one Lotus Domino server (running on a Windows NT 4.0 server), each with their own domain name and public IP address; the other one is hosted on an IBM AS/400, with its own domain name and public IP address. Both machines are behind a corporate firewall (CheckPoint software).
What I'm wanting is a box between the firewall and the two mail servers. Mail comes in, is sent to the SMTP scanner box, then sent on to the appropriate server after being processed. Vice-versa for outbound email. Can I do this with MailScanner/F-Prot/Sendmail on a Redhat box? or.... Can I configure sendmail to direct email to a specific server, based on the destination IP address? Pluses would be: - if the email is not intended for one of my IP addresses, or - if the email is not FROM one of my IP addresses, - reject the email to put a stop to any relaying attempts Tom Hightower Solutions, Inc http://www.simas.com Gerry Doris <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Sent by: cc: redhat-list-admin Subject: Re: SMTP scanning software? @redhat.com 06/18/2003 04:29 PM Please respond to redhat-list On Wed, 18 Jun 2003 [EMAIL PROTECTED] wrote: > > We need to set up an SMTP scanning server.

It's written in Perl and will integrate with sendmail tranparently ie. no changes required to a working sendmail config. It also works with Exim and Postfix but I haven't used those. MailScanner supports over a dozen commercial virus scanners as well as a few open source ones. I'm using F-PROT (commercial) and ClamAV (open source) together and am not aware of any virus' that have slipped through. Serious users often use multiple virus scanners since some are updated faster than others. Cron scripts are available to autoupdate the scanners. MailScanner will also work transparently with SpamAssassin to detect spam. My setup uses MailScanner calling F-Prot/ClamAV, and SpamAssassin. I've also installed Vipul's Razor and DCC which are used by SpamAssassin. If you aren't aware, SpamAssassin is a rules based program that scans the body of messages to score how "spammy" they appear. If the score exceeds a user set threshold they are marked as spam. You then process the spam marked messages however you chose (send to /dev/null, put into a hold directory, or just pass them on for the end user to deal with as they decide). If you take your time you can probably have the entire setup done in about 30min...it's that simple. Both MailScanner and SpamAssassin can be installed using RPM's. I believe I used an RPM for F-Prot too. Do a Google search for MailScanner and check out the testimonials. There are people using it that vary from home/hobbists to commercial users handling tens of thousands of emails/day. It's open source and is virtually real time supported by the author. -- Gerry "The lyfe so short, the craft so long to learne" Chaucer -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
