[Dovecot] virtual users

[tblader]

Hello All.
I've been reading the virtual user howto but cant get the login
working.  dovecot.conf is below [0] if anyone can offer some pointers.

I'm confused about the format of /etc/imap.passwd [1] also.  Does
the "pass" word in the example need to be plaintext, or the MD5
string from do.  Also, what is the significance of "{plain}"?

If there are docs I've missed, please RTFM with a link.
Thanks
