What I was wondering is....can someone help list the pro's and cons of skiplist and Bdb?

I found the following link to be very helpful

http://cyrusimap.web.cmu.edu/twiki/bin/view/Cyrus/WhatDatabaseBackend

'k, just read this, thx ... first question I have is what is /var/spool/imap/db? mboxlist? nothing else on that page appears appropriate, but just want to make sure ...

AFAIK, there is no such thing as /var/spool/imap/db (not in the IMAP spool). There will be something like /var/imap/db (in configdir), which is the BDB environment directory.

I have my imapd.conf file setup to point to /var/spool/imap ... not sure why I did this, but I've had it like this forever now ... same as the default /var/imap ...

So, based on the above ... if I were to switch *everything* to skiplist, then that directory would go away?

It wouldn't go away by itself, but you could remove it.

'k ... just to make sure that I fully understand though ... as long as I use Berkeley DB for *anything*, that directory needs to exist ... ? For instance, if duplicate_db == db3?

Yes. I you use BDB for any of the databases, then you will have a <configdir>/db/ directory.
