Thank you Dominic,

I am afraid that our active mail gateway server is rather old...

We are preparing a new gateway server which is almost ready (with new 
software), but I don't feel it's fully production-ready, so it's not yet 
in production!

Thank you, I will definitely check the directives you advise!

Any and all assistance is very important to me!

Cheers,
Nick
