I use Exchange that is configured to use the ISP as a Smart Host. I've just put out an email to them to see what mail server they have (they don't allow Telnet, so I couldn't get their banner :-) Tom www.isaserver.org/shinder -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: Friday, January 18, 2002 9:41 AM To: [ISAserver.org Discussion List] Subject: [isalist] Re: Bug in ISA SP1 SMTP filter http://www.ISAserver.org I'm working with the ISA QFE team to solve this. 1. How were you able to determine that Postfix mailservers were the problem? 2. Do you have any packet traces to share with us (NDA applies, of course)?

The problem was that eversince I upgraded ISA server to SP1, some people were unable to send me mail. (I publish an Exchange server behind ISA). People got an error message: 5.3.3 Unrecognized command. After a while I found out it affected only those people (or their ISP's) that were running the Postfix Mailserver. Disabling the SMTP filter solved my problem. After I found out, I read on a dutch forum that it's a bug in SP1. A fix will probably released soon. With regards, Angelo Höngens.
