Hi Sam,

We have solved this difficulty in VOPmail by requiring ESMTP authentication
before opening an unapproved IP for relay. This of course requires your
customer to use a mail client that supports ESMTP authentication.

If your NTMail user repository is stored in either the NT SAM or an ODBC
DSN, we have just introduced a light, relay-only version of VOPmail for
$175. This version could authenticate against your NTMail user repository
and be used only by your roaming users.
