Alessio, thank you for your very complete answer and evalutation of the 
problem. Since you have already set up a test environment, can you do me 
a favour and try one more thing?
Specify - in dovecot.conf - the port on which imap should listen to, and 
see if it makes any difference to vpopmail.

Thank you again very much for your cooperation.
