RE: [IMail Forum] Imail and Antivirus......

Dave,   You need an SMTP scanner which is able to decode the mails while scanning them.   There are many products on the market, some of them use standard scanners to scan the decoded mails. One example is McAfee's Total virus defense, another one is MailWall at http://www.omniquad.com/   However, if you want to combine SMTP and HTTP and FTP scanning, I'd prefer a "professional" security solution like Checkpoint's Firewall-1 or similar products which have standardized AV protocol.   Marius -----Original Message----- From: Eric Shanbrom [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 06, 2000 2:19 PM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Imail and Antivirus...... NO   How come? because Attachments are MIME encoded and will have the virus signatures encoded so they won't be recognized by standard AV software.   Eric S ----- Original Message ----- From:        To: [EMAIL PROTECTED] Sent: Wednesday, July 05, 2000 6:25 PM Subject: RE: [IMail Forum] Imail and Antivirus...... Here's something I'm a bit curious about.   Can I use a regular virus scanner, like NAV 5.0 for NT, to scan user's folders? Seems to me a pretty easy quick way to prevent users from DL ing virus infected files. If no how come, if so what are the ramifications?   Also.... If I turn on 'relay for specific addresses' option in SMTP security and I don't add any addresses will that automatically engage the smtp auth feature?  Along those lines, if an email client pgm is set to send an auth u and pw, and the server does not require one, does that cause a problem?    Dave -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Len Conrad Sent: Wednesday, July 05, 2000 12:35 AM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Imail and Antivirus...... We use Norton AntiVirus for Internet Email Gateways (NAVIEG). It works very well. My only complaint it that it has to antispam features. Norton has promised an upgrade soon, but I'm still waiting.   Since we use Len Conrad's IMGate servers to process the incoming mail, we do not have to have the NAVIEG server in DNS, which makes it almost invisible. Matt, If you have the NAVIEG box (I assume it's a separate box) "behind" IMGate, why would you be concerned about NAVIEG's absence of an anti-relay feature? At your router, you could block all traffic from the "outside" to the public ip of the NAVIEG box. (this is great advantage of having the AV on its own box separate from Imail) You guys run a pretty heavy level of mail traffic, does NAVIEG impede your mail throughput noticeably??
