[Dovecot] POP users see duplicate mail after upgrade (was Re: One user having reproducible IMAP issues)

[Alex Boster]

Is there a way to upgrade from rc26 to rc27 without causing our POP  
users to see duplicate new mail?  That was a problem last week with  
the 0.99 to 1.0rc26, and the other admin on the box is reluctant to  
upgrade again if that is going to happen again...

Thanks,
AB
