lmtp connection refused

[Kevin van Haaren]

I'm having a problem delivering mail to cyrus imap (version 2.0.12) 
running on a Debian Linux PowerPC box (kernel 2.2.19pre17).  I'm 
using postfix for smtp.  I have no problems connecting to the imap 
server from the client side (using Mulberry as the client).

Problem is when deliver gets called.  I get an error in syslog:
Apr  8 10:18:51 mojo deliver[6906]: 
connect(/var/lib/cyrus/socket/lmtp) failed: Connection refused

and deliver hangs.

my postfix master.cf file has:
cyrus     unix  -       n       n       -       -       pipe
     flags=R user=cyrus argv=/usr/bin/deliver -e -m ${extension} ${user}

and main.cf has:
mailbox_transport = cyrus


Thanks - Kevin
