Spot on, you hit the nail on the head. Once I tried a "proper" test it works.

Yes, telnet wasn't a valid test. I spent the entire night on this issue last
night before emailing the list for help, only to wake up this morning to your

All is working fine now and a big problem is resolved. Thank you very much,
it's much appreciated.

Michael.
