This is the response I receive when attempting to validate our mail server:

MX records
Preference Exchange IP address (if included)
10 mail.xxxxx.org [xx.xxx.62.125]

221 2.0.0 excsvr03.xxxxx.ORG Service closing transmission channel
[Connection closed]

The invalid response is highlighted. We can send and receive mail fine however another ISP has complained that this invalid response is causing their particular mail server to reject us. We are not behind a firewall here.

OS: Windows 2000 SP4
Exchange Server Standard Ed. SP 4 (6.0.6487.1)

Anyone have any ideas? Any help is GREATLY appreciated. Thanks in advance!
