Hi Aki,

Thanks for the tip.  This works, but when implementing it I discovered 
that just setting the password type generically to 'CRYPT' will let 
Dovecott use the built-in OS crypt decoding of the scheme number already 
encoded in the password.  It now automatically detects MD5, SHA256, and 
SHA512.  If my Linux distribution supported blowfish it would support 
that too.
