Port 587 is the `submission' port. It sounds like your Postfix isn't
listening on that...
You're right, That's it in a nutshell. I confess that I didn't
even consider the possibility that nmh would be using 587 rather
than 25... although it is certainly more correct for it to use
587 when submitting.
Thanks! I'll tweek Postix and turn on local submission via 587.
so you need a `post: -port 25' in your ~/.mh_profile.
Or just get Postfix to open up 587.
