Dominic, thanks for the reply and I apologize for the failure to follow
list etiquette, I am so used to cleaning stuff up I just did it without
thinking..

Just to be totally clear on your response.. you said:
>It suggests that the
>remote host for "1domain.com" is refusing the null sender.


Remote=external mail server for idonails.com [209.42.34.104]
or
remote=server where the domain is hosted [64.79.202.131]

I see it as server.wwwebserv.com refusing the mail because it can not
verify supplysource1@??? - server.wwwebserv.com thinking because
idonails is a local domain, checking locally to not find a user of
supplysource1. If this is correct, then it is my problem and I need to
resolve this.

Here is the unaltered version..
basic issue: supplysource1@??? with in-house mail server can not
email anyone on the server where the domain is hosted..
