Re: Delivering mail through nmh via SMTP...

Personally I  think this was a  mistake. SMTP is port  25, SUBMISSION is
port 587.  If something says  SMTP, what comes to  mind is port  25, not
587.

$ grep smtp /etc/services; grep submission /etc/services
smtp            25/tcp          mail
smtps           465/tcp                         # SSL-wrapped SMTP
submission      587/tcp         msa             # mail message submission
submission      587/udp         msa             # mail message submission
