mail not being deleted (ie arriving again and again)

hey all,

excuse me if this has been asked before, I've had a fair look around,
but haven't been able to find an answer. 

My setup is as such - I have a linux box that runs my mailserver, and I
check my mail using pop.  I've just setup Zoe running on the linux box,
and added the account to check localhost with my username/password, and
smtp to localhost again with my username/password.  The only checkbox
I've selected is "forward messages to server".

My problem is that after forwarding an email with some attachment emails
for import, I then found that every time I checked my mail I got those
same emails again and again.  I turned on debug on zoe and can see the
messages being deleted, but it doesn't seem that they're deleted from
zoe.  The output from the debug (small snip) is:

05/04 22:09:56 (Debug) SZPOPSession.run: aLine: RETR 10
05/04 22:09:56 (Debug) SZPOPSession.run: someTokens: [RETR, 10]
05/04 22:09:56 (Debug) SZPOPSession.run: aCommandName: RETR
05/04 22:09:56 (Debug) SZPOPSession.run: aCommand: RETR
05/04 22:09:56 (Debug) SZPOPSession.run: someTokens: [10]
05/04 22:09:56 (Debug) SZPOPSession.run: Done: RETR
05/04 22:09:57 (Debug) SZPOPSession.run: aLine: DELE 1
05/04 22:09:57 (Debug) SZPOPSession.run: someTokens: [DELE, 1]
05/04 22:09:57 (Debug) SZPOPSession.run: aCommandName: DELE
05/04 22:09:57 (Debug) SZPOPSession.run: aCommand: DELE
05/04 22:09:57 (Debug) SZPOPSession.run: someTokens: [1]
05/04 22:09:57 (Debug) SZPOPSession.run: Done: DELE

obviously here I've got 10 emails, and you can see where outlook checks
them (RETR) and then goes to delete them (DELE).  This process repeats
over and over again, each time I check my mail I have the same 10
emails....  

I'm assuming I've misunderstood how to setup Zoe - any advice would be
greatly appreciated.

cheers
