Problems with repeated download of messages from pop3

[Gene Rackow]

Been there, tried that, well sorta anyway.  My mailbox
numbers have grown to that level all on their own.

I have not seen the UID as an issue.  IF Outlook gets
interrupted in any number of ways when popping a message
from the server, it has a good possibility of forgetting
what it has or what it's done.  Then on the next connection
you get a repeat of all the old messages onto your client.
It doesn't matter what the UID of the message is, the failure
is all on the outlook side of things.

Ways to mess it up include any number of network blips that
temporarily disconnects the client from the server.  There have
been other cases where the anti-virus on the client will trigger
on something and stop or abort the rest of the message
from downloading.  Still others where the outlook files get to
big and then everything just blows up.

If you want something that is less prone to failure, you need
to get rid of Outlook, or as some line to call it "Look Out!!"

PS: check the headers for a long used header to be seen by outlook users.
