I have not been able to get packet traces yet (production box and don't 
want to turn SMTP filter back on) but I had problems getting any mail at 
all from Domino servers this morning- the sender received the following error:

 >SMTP Protocol Returned a Permanent Error 500 5.3.3 Unrecognized command

Turning off the filter fixed it.

Good luck!
