No Mail for 4 days now - Arghhh!

Hi Folks - I've got a mail problem and if anyone could help me pin it down
I'd sure appreciate it as I'm having a hard time with it...
I'm running ISA 2004, and have been for years, with mostly no issues. I was
using both Exchange and a separate IIS5 server as a relay however I recently
phased that out and went back to only using Exchange.
As such it's pretty straightforward: ISA 2004 w/Exchange 2000 located behind
it.
The problem is that other mail servers can't connect. The ISA logs show
every mail server that tries ends up with;
Failed Connection Attempt and error code 0x8007274c
The Exchange machine has ISA as it's default gateway, no firewall client.
The ISA 2004 machine has the standard SMTP rule created for All Networks
(and localhost) and it points back to the Exchange machine's IP address.
Internal email works fine - the mail server is working. I tried disabling
the SMTP filter and have also tried deleting the rule and re-creating it.
Does anyone out there know what could cause this?
