The irony is we are not listed on SORBS.net, I don't know whose IP address that is (not ours).
We're using GFI Mail Essentials but I tested with that service not running and it returns with the exact error message. I'm also checking with GFI, awaitiing their response. Frustrating!!

The dynamic IP listed is always the same, it looks like DSL.NET's. Maybe I should call them now?
I went through DNSstuff.com, checked through the MX, the Reverse DNS, and spam lists - all cool.

2. Check your reverse dns records
3. If you don't have SPF, make a DNS SPF record. SPF stands for Sender Policy Framework and each domain should have a SPF record in DNS. See www.openspf.org.
