Hi I tried the HELO instead but to no avail, this seems to have just
started since I moved the SMS server (with exchange)one hop away from
the ISA firewall server.
Thanks, Peter
Try sending to that particular domain (and others like it) with the HELO
instead of EHLO setting in your SMTP server of Ex2K.

Subject: [isalist] Some email gets bounced, just some??
http://www.ISAserver.org
Hello again, I am having a strange situation on my ISA firewall/Exchange
2000 configuration. I publish to a secure mail server, the exchange 2k.
Mail goes out just fine to everyone, however some of the replies get
bounced as NDR. Here is a bit more from the NDR,
"A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
fname@xxxxxxxxxxx
SMTP error from remote mailer after end of data:
host mail.company.net [xx.xxx.xx.25]: 500 5.3.3 Unrecognized
command"
Could this be a content filter issue or mail application incompatibility
issue. Any help would be appreciated, Thanks. Peter
