Does that mean that those customers run their mailserver on dynamic IP

Hi Sven,
Yes, I'm sorry, forgot to give that information. They might be running
dynamic IP adresses/domains,

You must setup SASL and only let authenticated users relay through this

You could put your customers on a private network not accessible by the
public (and I mean VPN kind of private here rather than RFC 1918 kind
of private). However, that's just moving authentication and encryption
to a different layer.
Why do you want to avoid using SASL

SASL and VPN would mean that all customers would need a separate account
for their outgoing mail, and that would be a too big project to go ahead
with.
As most of their servers is BlueOnyx it is not really possible to make a
centralized user / password database.

Hi,
Just create sasl account for allowing to relay to those authenticated
users. But be very careful on what you're users send though it because
if you're custommers start sending mail considered spam in two weeks

This option :
I was just thinking about another option. I might be able to make a
small program that analyzes the logfiles for each server, puts it in a
database with a timestamp, and then make it a POP/IMAP before SMTP.
That would be secure enough right?
