Question : SMTP; 554 5.4.0 Too many Received: headers

Exchange Server (2003) uses Quantum Exchange Connector to pop emails down from hosted pop accounts.

This is intermittent but some emails comes through to my organization and some do not. The sender receives:

Answer : SMTP; 554 5.4.0 Too many Received: headers

Here is a solution that may help someone down the road:

I had a PCI parallel card with me, and the 4250 has a parallel port.  I installed the card, hooked up a parallel cable, and changed the port on the printer properties....and it all works fine.  Nice and fast like it's supposed to.  I don't know WHY, but it now works great.
