Well, DNS didn't work, as it refused to resolve any addresses, even local ones..
Ip would work without issue.
I bit the bullet and just did everything from scratch, as I don't have time to download 5, install it, then install 5.5 then 5.6 , then 6.01..

The only issue I'm having now is that of copying of some maildir stuff, for a user that did everything via IMAP.
What a headache. On the plus side, I now have hylafax respnding through 4 different modems on that machine.

Thanks for the help, wish I could have read it earlier .
