Probably not the issue here. Laurent still has all his mail on the server, and 
I don't think two mails on the server have the same UID.
However, if you don't leave the mail on the server, it might indeed happen 
that UIDs are recycled. Because of this, the POP3 resource deletes already 
seen UIDs from the config file once they are deleted from the server. This is 
even unit tested.
So I doubt recycled UIDs are a problem for the POP3 resource, and in any case 
not Laurent's problem since he leaves all mail on the server.

Regards,
Thomas
