Details

Mozilla Mail uses the @isp.com part of the sender e-mail for the fully qualified domain name sent to an SMTP sevrer during a HELO request. As such, user Joe Bloggs, with email of jbloggs@isp.com would be sending out emails with a HELO of 'isp.com'. It is unlikely that this will be a fully qualified domain name that points to the sender's real IP, and such is likely to violate section 4.1.1.1 of RFC2821: Received: from user-123.isp.com ([123.123.123.123] helo=isp.com) by mail.isp.com with esmtp (Exim 3.35 #1)
