Kevin.. it works if you give the proper machine name in the HELO
MCI's iNOC pretty much confirmed there was a filter in place, as did the systems person I finally reached thanks to some key responses from this list. Probably a spam relay block of some kind. The '550 Access denied' reponse is that they use in their SMTP filters. postoffice.reston.mci.net was down for two hours and counting when I got them on the phone, so with local MCI users not being able to send mail, I was not a high priority :) At any rate, the 'HELO netins.net' statement is a result of host masquerading (DMnetins.net). Same thing happens with a FQDN : 220 postoffice.Reston.mci.net ESMTP Sendmail 8.8.5/8.8.5; Wed, 24 Sep 1997 15:16 :25 -0400 (EDT) HELO worf.netins.net 250 postoffice.Reston.mci.net Hello kevin () worf netins net [167.142.225.4], pleas ed to meet you MAIL FROM:<kevin () netins net> 550 Access denied Kevin
