Thanks for the rsync advice, I'll go for that.
By the other hand, I'd prefer not to copy the data over /var/lib/imap,
since the BDB4 versions differ. Instead, is there any way to reconstruct
the databases under /var/lib/imap just from the content that it may find
under /var/spool/imap? (where the mailboxes are stored and are gonna be
rsync'ed).
Thanks,
Fabio
