Outgoing Mail Server (SMTP) Port and
Password Authentication Instructions
Because of the increasing amount of viruses and spam abuse
MCN customers and CVC customers:
1) must only use the MCN outgoing mail server (mail.mcn.org)
2) have Password Authentication set in their email program.
We recommend ALL customers do these two things...
If using internet connections other than MCN (i.e. satellite, Comcast cable, AT&T DSL, etc)
and you're experience problems with sending emails
changing the outgoing server port number to 587 or 465 can remedy the situation.
Instructions on how to change these settings in the most popular email programs are below.
Click once on the name of your email program (it will be blue and underlined).
You'll be linked to directions on how to check your outgoing mail server is correct
and set Password Authentication in that program.
