Can you expand on "email sender script" updating HELO property? Are you

What email server program are you using? If you've got mis-matched HELO
and/or rDNS you'll be blacklisted within a very short time as a spammer.

Different ASP pages on different domains (web sites, I should say) use
the same Persist Email component to send notification (order
confirmation etc.).
All of them have the same HELO (DED516GBAU.maximumasp.com) which is
206.196.29.69
Until today that IP was resolving to an ARPA address. Now there is a
PTR record so the IP resolves back to DED516GBAU.maximumasp.com.
Even though I send emails from different web sites with different
"FROM" addresses, HOST is always set to DED516GBAU.maximumasp.com
along with HELO. Do you mean this cause a problem?
