It seems that the 'Leave Messages on Server' is having problems of
late. Last four weeks the server is sending the same e-mail, even though
I haven't delted the e-mail. I have tried four different email programs
incase this was the problem, but alas it does not solve the problem.

The emails that the server is sending again and again are a mixture
of not only proper emails that are still in the inbox, but also Spam
thats been sectioned off and then deleted.


The remove email from server option is also ticket, so this cannot
be the problem.

A couple of time it has also sent the same email upto seven times.

1and1s answer seems to be using IMAP not Pop3?
