When a site administrator creates a mailing list which includes an external email address (i.e. not belonging to the site administrator's domain).
In this case, when a mail arrives from outside, for the firstname.lastname@example.org, then the top level sendmail daemon running on the EPL server correctly routes the email to the site.com FST. The chroot()ed sendmail then hands off the email content to the majordomo handler.
The majordomo handler then re-invokes sendmail to deliver mail to its recipients based on MX whose domain is external to the box.
This creates an outgoing SMTP connection, whose conversation starts with EHLO <site.com>
We have a fix for chroot()ed sendmail.cf which will correct the EHLO strings.
Run the script on the server which will modify each site for smart relay.
