Of course. I'll explain the setup some more:

[Internet] - [Us] - [Large proprietary mailserver]

Currently all that's available is the NT mailserver. The first step is that
we want people to be able to 'opt out' of using the large proprietaty
mailserver, and forward their mail to another account.

In order to do this, we take over the primary MX of the domains in question,
and intercept any mail sent to us.

If it turns out that the user has decided *not* to opt out, we need to
deliver the mail to the large proprietary mailserver anyhow. The only way we
can do that is to connect to their port 25, and drop off the mail as if they
were still primary MX.

Some kind of ahu%ds9a.nlbigntmailserver.com hack is in order - except that
doesn not appear to work.

Regards,

Bert Hubert
