Keep a copy of the UID's you have downloaded locally, compare against the
UID's on the server and only do a GETALL on the ones you haven't seen before
and then store those UID's too.

This process will get progressively slower as more and more e-mails are left
on the server though.

CFX_POP3 has a GETUIDLIST function which just retrieves the UID's of the
mails on the server and makes the process lightening fast but it only works
on 32-bit CF installations on Windows so it's life is limited now.

It looks as though this issue still recurred though I have no new information 
to go with the issue.  I will probably make some adjustments later on to see if 
that helps
