Ditto. I use Postfix. The Postfix box is the only path for mail in and out of the network. Never had a problem with it and the PIX. I also use it to offload spamfiltering. jas -----Original Message----- From: firewall-wizards-admin () nfr com [mailto:firewall-wizards-admin () nfr com]On Behalf Of John Adams Sent: Thursday, May 24, 2001 6:39 PM To: Smith, Gary (SCOTAM) Cc: 'firewall-wizards () nfr com' Subject: Re: [fw-wiz] RE:Exchange Server 2000 and Cisco Pix (Christoph Puetz) On Thu, 24 May 2001, Smith, Gary (SCOTAM) wrote:

We have had no problems using fixup with qmail and sendmail. Because of the insecurity of the exchange server, we typically place a qmail host out on the edge, harden that host, and place an appropriate smtproute to it to forward to exchange. For users sending mail through the smtp part of exchange, we force them to use VPN or webmail. You really don't want exchange exposed to the Internet, but that's my opinion. -john

Microsoft refers to Cisco without really being specific - at least I could not find the solution at Cisco's web page. Anyone here knows what I have to do? Here's MS solution (Article ID: Q295164) for the problem: "RESOLUTION To resolve this issue, disable SMTP inspection on the firewall. If you do not know the command to disable SMTP inspection, contact Cisco." Is this the fixup command I have to use and disable smtp?
