dovecot-postfix & Java

[Thufir]

Having stumbled around a bit, I suddenly noticed:

http://packages.ubuntu.com/precise/dovecot-postfix

Don't know why I didn't notice that earlier in aptitude!  Anyhow, what 
are people's thoughts on this?  I don't see any documentation, at least 
not off the bat.  It uses IMAP or POP3? 

I want to use Java to parse messages, and that seems difficult with just 
postfix.  Apparently doveadm works well..?  You can use Java with it?



thanks,

Thufir
