I've been using procmail for a long time but I'm open to trying something 
else. A look at the wiki indicates that Dovecot uses a Sieve plugin to 
accomplish filtering.

What other "better and easier" methods are you referring to?

Are there any conversion tools for converting files of procmail rules to 
Sieve syntax?

The bulk of my rules look for the Mailman List-ID header and file to a mbox 
mailbox named after the list. For example, here's my Dovecot list rule:

:0 :
* ^List-ID:.*dovecot
mail/Lists/Mail/Dovecot
