Starting tmda-ofmipd with tcpserver and stunnel

Reply To:
User-Agent: Unison/1.7.6

Qmail,vpopmail,tmda-1.1.7 are running on gentoo.

My mail client is Mac OS X 10.4.7 Mail.

I tried to adjust the scripts in the contrib directory but I've clearly 
missed something.

I have a file called run it contains
#!/bin/bash
# Startup script for tmda-ofmipd daemon
#
exec /usr/bin/tcpserver -v -P -R -x /etc/tcprules.d/tcp.tmda-ofmipd.cdb \
    -c 40 -u 89 -g 89 \
    mail.ercolano.net 8026 \
    /etc/tmda/stunnel/stunnel-wrapper

My stunnel wrapper has:
#!/bin/sh
exec /usr/sbin/stunnel /etc/tmda/stunnel/stunnel.conf 
2>/var/log/tmda-ofmipd-starttls-stunnel-wrapper

My stunnel.conf contains:
exec =     /etc/tmda/stunnel/tmda-ofmipd-wrapper
execargs = /etc/tmda/stunnel/tmda-ofmipd-wrapper
cert = /etc/tmda/stunnel/stunnel.pem
client = no
foreground = yes
protocol = smtp
debug = 7

My tmda-ofmipd-wrapper contains:
#!/bin/sh
exec /usr/src/tmda/tmda-1.1.7/bin/tmda-ofmipd -f -1 -d -R 
imaps://mail.ercolano.net \
                -S /usr/src/tmda/tmda-1.1.7/contrib/vpopmail-vdir.sh \
                2>&1

The Mac Mail app smtp server setting is set up to use an SSL connection 
to port 8026.
When I try to send a test mail message I get the following debugs:

Any thoughts as to what I'm doing wrong here?

By the fact that it knows about the imaps authentication it would 
appear to at least be trying to start tmda-ofmipd.

I can successfully use tcpserver to invoke tmda-ofmipd "directly" in 
single session mode with no stunnel (and the Mac Mail app not using SSL 
and the mail app going directly to port 8025.)
