Oh,
Two possibilities on what you are experiencing
1) other mail servers attempt to block spam are checking your
address->IP and the address (domain.com) that you are sending from
does not reverse dns to that IP.
2) you to setup a mails sever that will allow this internal address
to relay out thru it.

Prior to yesterday I had the system var MAILSERVER=10.10.20.12 in
witango.ini. To remove some of the traffic from my email server I
changed it to use the Microsoft SMTP server located on the witango/
web servers.
Now I have started getting quit a bit of undeliverable email with the
following errors
<ics7 #5.5.0 smtp;521-EHLO/HELO from sender 207.170.44.200 does not
map to ics7 in DNS>
Or
<ics9 #5.5.0 smtp;521-EHLO/HELO from sender 207.170.44.200 does not
map to ics9 in DNS>
Can someone help me with this?
