[Dovecot] POP3 locking

[Adrian Overbury]

So, the final determination here is that newer versions of Dovecot than 
the one I'm currently running will successfully lock up a mailbox and 
limit access to it to a single session while that session exists (up to 
a finite timeout, which I think is two minutes), right?  Okay, then. 
Has anyone built packages for Ubuntu Dapper Drake from the latest 
sources, then?  I'd appreciate being able to get my hands on thoses.
