Thanks, and I've tried setting my options in webmail prior to sending, but I am still getting errors when I send to some, but not all domains:

Final-Recipient: rfc822; customerservice@oncall-pc.com
Original-Recipient: rfc822;customerservice@oncall-pc.com
Action: failed
Status: 5.0.0
Remote-MTA: dns; oncall-pc.com
Diagnostic-Code: smtp; 550-Verification failed for
<ajackson@solutionsforcare.org> 550-The mail server could not deliver mail
to ajackson@solutionsforcare.org. The account or domain may not exist,
they may be blacklisted, or missing the proper dns entries. 550 Sender
verify failed

How do I allow a distant mail server to verify sender's validity? I get the feeling that this is some anti-spam measure that I'm up against...

Thanx

Allen
