Oh I misunderstood.  I thought you were suggesting I stop trying to get 
this to work,
give in, and *just use another email client*.  My apologies.

I was looking for another iPhone email client which was free and did 
iMap. I failed. I think I'll
just have to pay for one and try it.

I've run out of time just now.  I'll try again soon.

Thank you.
