Yes, you will want to disable the SMTP fixup. It causes a lot of problems with exchange. Use the command: "no fixup protocol smtp 25" to disable it. It acts as a proxy to the smtp server by filtering the commands that it sends to the server. In doing this, it tends to cause problems with the sending and receiving server. There is also a known bug that keeps biting me regarding how the PIX handles the end of a SMTP message. If the end of message signifier . <CRLF> come in on seperate packets, the pix doesn't recognize it as the end of the e-mail. Because of this, the PIX never acknowledges that the message was received successfully. So, my local SMTP server keeps resending the message to the client. There is a documented PIX bug on cisco's site. They have fixed the bug and it is in the newer releases of PIX software. Check out the bug if you have a CCO login <http://www.cisco.com/cgi-bin/Support/Bugtool/onebug.pl?bugid=CSCds90792> -----Original Message----- From: Christoph Puetz [mailto:puetzc () yahoo com] Sent: May 21, 2001 11:55 AM To: firewall-wizards () nfr com Subject: [fw-wiz] Exchange Server 2000 and Cisco Pix Hello wizards, I have a newly installed Exchange Server 2000 behind my Pix and did receive an error from a mail client when trying to connect to the Exchange server. 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? Thanks for your help in advance!
