one of my clients has been having somewhat intermittent problems sending mail to addresses.  their domain is not the main domain of the server.  i've gone ahead and added SPF lines to their zone files, is this going to do the trick or are there some other issues with comcast that i can't find info about?  this is the error:

SMTP: Address rejected by host
Host '' says:
550 [PERMFAIL] requires valid sender domain


Reporting-MTA: dns;
Received-From-MTA: dns;
Arrival-Date: Mon, 4 Oct 2004 16:02:30 +0100

Final-Recipient: rfc822;
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;551 This is not a relay host - mail must be to or from host domain.
X-Display-Name: Name - OffSite Mail

if anyone has any insight as to what's going on i would be very appreciative!!! thanks in advance!
