If you're able to access via HTTPS from inside, but can't even connect
from outside, it's probably a firewall issue, and not something we can
help with.

1.  Are there any other HTTPS resources on that server that you can test?
If you can access other resources but not to Mailman, perhaps your
frontend webserver (Apache?) is not configured the same for HTTPS
as it was for HTTP.
2.  Use tcptraceroute from outside to port 443 on the Mailman host to
find out where the connection is broken.  The " refused to
connect" is often misleading -- in many cases the attempted
connection never reaches , but the error message says
"refused".
3.  Double-check your firewall configuration, and also the network
filter configuration of the Mailman host.

Our mailman server is on DMZ and a couple of month ago was changed to work 
https.
