[Dovecot] qpoppers XUIDL

[Chris Wakelin]

We can't make them compatible, but qpopper writes them into a X-UIDL 
header which we can reuse (in Dovecot 1.0-alpha3) by setting

pop3_reuse_xuidl = yes

This means new messages will get a Dovecot UIDL, but existing messages 
will reuse the qpopper one (so users won't download the mail again with 
qpopper -> dovecot, but will, for newer messages, with dovecot -> 
qpopper, should you ever need to do that!)

See http://wiki.dovecot.org/moin.cgi/Migration

The downloading over and over may be Outlook not liking the default 
pop3_uidl_format. See the dovecot-example.conf for suggestions.

Best Wishes,
Chris
