[Dovecot] courier-dovecot-migrate.pl maintaining order of pop3 uidl's

Hi there,

I've just been experimenting with the latest courier-dovecot-migrate.pl 
script and I notice that it favours keeping pop3 UIDL ordering rather 
than IMAP UID preservation. There is this comment (line 312):

     # POP3 clients may want to get POP3 UIDLs in the same order always.
     # Preserve the order even if it causes IMAP UIDs to change.

Does anyone have details as to which clients this actually causes a 
problem with? If it's some really old software then perhaps we'd prefer 
to keep the imap UID's the same but change the POP3 UIDL ordering (not 
the UIDL numbering though of course)

Thanks,

Mark
