[Dovecot] Configuring Dovecot & Snarf plugin for the first time

[Jeffrey Ross]

I've been using uw-imap for some time on my linux system and have been 
running into issues with it so I've decided to move to Dovecote, so far 
it seems to have solved the issues I've been having however I need/want 
to move the incoming emails out of /var/spool/mail/{user} in the same 
(or similar fashion) that uw-imap did, and I found the snarf plugin.

However whenever I enable the snarf plugin using the example on the wiki 
page my email is not loaded and when I remove my configuration for snarf 
my email re-appears.  Based upon what I can tell the snarf plugin is 
either not loading (but I see it listed in the logs) or simply not 
working (which is probably because its not configured properly).

The system is Fedora 16 (x86_64), the MTA is Exim, and Dovecot is 2.0.21 
(version supplied with Fedora).  I know I'm making a newbie mistake.

Any guidance would be appreciated.

Thanks, Jeff


dovecot -n provides the following:
