[Dovecot] Snarf plugin

[Jeffrey Ross]

I've now upgraded dovecot from 2.0.21 to 2.1.10 and the good news is I no
longer see dovecot crashing when loading the snarf plugin however snarf
still does not do anything except make the inbox disappear.

I've come to the conclusion that either snarf does not actually work,
possible, but I doubt it, or more likely I have a configuration issue
preventing it from working.

The system is simple, all email is stored in /var/spool/mail/{username}
and I want all the mail moved to ~/mbox when the user logs in via imap,
similar to uw-imap.

Any guidance would really be appreciated.

Thanks, Jeff
