Thank you Brother Maynard. (If only I had a Holy Hand Grenade to go with 
it...) ;-)>

No, 1 would be slower than 4 and I am already getting 4 since it's being 
controlled at their end. I'm trying to be polite and limit only my 
outgoing connections to their server to be 4. My mail *is* being 
delivered, I just want to eliminate the 400 series code saying 'Too many 
connections'.

NEEY!
