Well, initially I just wanted to point everything to user1. Just to try
but that didn't work.

I don't mind, but I don't have it. It's back at home and I'm at the
office. (it's 8pm and I'm still at the Office!!)

Let me get it tomorrow maybe.

Actually its cyrus users. It's a different beast compared to just
running a _normal_ IMAP like dovecot. It's being delivered to
/var/spool/imap/(can't rememeber)/u/user1/

I just put it as user1 for the time being.

Right now, I'm ok with anything. As long as it works and then i can
solve it from there on.

Ah... Okay, in that case, the above answers can't really be helped by you. 
Don't mean to offend but cyrus is a different beast with a separate
mailstore etc.
It's just different and it not as simple as it sounds.

Hmm... I don't think it applies to cyrus since postfix talks to the LMTP
which talks to cyrus. Postfix and cyrus don't commicate. They just know
that they hand everything over to LMTP.

Thanks anyway..
