Hmm.. disagree with your analysis. Problem isn't selected *originators* - it is
selected *destinations*, and servers, not just user accounts from the look of
most returns.
Probable reason is differences in their configuration to reject forgery, zombie,
and spam sources.
What I *suspect* is the cause:
1) As you are not posting here FROM the server with the problem, I cannot see
what it is HELO'ing as, but I suspect that said HELO is something that does NOT
forward/reverse match the IP from whence the connection originates.
Some server rulesets (not just Exim) may be configured to reject on that sort of
mismatch as a possible forgery.
2) You have '
www.ithou.org' as the return for the IP lookup, which won't be an
exact match to plain 'ithou.org'. Some server configurations may not accept that
either.
It would be *much* better if that entry were simply 'ithou.org' (additional
entry for '
www.ithou.org' recommended as well). Your httpd should be set up to
respond to either 'ithou.org' or '
www.ithou.org', as is common.

Just send a message to:
askbill@???
FROM your ithou.org box, not some other account.
I can probably confirm the above 'suspicions' from my server logs, then advise
the next step(s).
Best,
Bill
