[44net] hotmail

We're having some problems with 44net email to and from hotmail.com. Mail from that domain is getting delayed, sometimes for hours, and mail going to addresses in that domain is received by the server but not delivered to the users mailbox.

I think I've fixed the delay problem by adding more IP addresses to the greylister 'whitelist', but I don't know of anything I can do about the delivery problem. - Brian
