couldn't connect to lmtpd_

Hello,

We're running OS X Leopard Server 10.5.8 on an Intel Xserve. These messages are filling up my log and users cannot receive mail, although there are plenty of messages queued.

Aug 22 09:39:51 corpserv postfix/pipe[775]: E5117D55CB: to=<wendyb@corpserv.com>, relay=cyrus, delay=2411, delays=2410/0.02/0/0.9, dsn=4.3.0, status=deferred (temporary failure. Command output: couldn't connect to lmtpd: Connection refused_ 421 4.3.0 deliver: couldn't connect to lmtpd_ )

I have run mailbfr -b, mailbfr -o and mailbfr -f, to no avail. Does anyone know how to fix this issue?

Thanks,

Patrick
