port forward to MS Exchange IMAP


I'm trying to open a hole in my firewall so that a 
user can pick up his IMAP email (actually the owner).

I'm trying to use ipmasqadm mfw to do the job like this:

# ipchains -A input -p tcp -y -d 143 -m 1
# ipchains -A input -p tcp -s 0/0 -d 143 -j ACCEPT
# ipchains -A input ! -y -p tcp -s 0/0 -d  -j ACCEPT
<other stuff snipped>
# ipchains -P input DENY

# ipchains -A forward -d -s -j ACCEPT
# ipchains -A forward -d -s 0/0 -j ACCEPT# ipchains -A
forward -d 0/0 -s -j MASQ
# ipchains -P forward DENY

# ipchains -P ACCEPT

# ipmasqadm mfw -I -m 1 -r 143

When I try to telnet from the outside to port 143 the cursor 
sits there, and I see no reponse.  The IMAP server at 
can be reached from the firewall.  NO LOG ENTRIES in
/var/log/messages or any other log I can find.

I'm pretty sure I compiled with the right options set.  At least
I didn't find anything in the IP-Masq HOWTO that had to be set 
that wasn't set.  I haven't found anything in a Google search 
that helps either.

Right now, I'm a bit stuck
