[Error sending: Connection failed to smtp.usm.edu,25: Connection timed out]

[litd99]

Hello,

I'm using Alpine 1.00 on Ubuntu 8.04. However, when I send email at
home using cable modem (wired USB interface or wireless), it showed
the following errror msg

[Error sending: Connection failed to smtp.xxx.edu,25: Connection timed
out]

This is my SMTP server setting

SMTP Server (for sending) = smtp.xxx.edu/novalidate-cert

It works fine if I send email using University net.

Thanks!

Many DSL and cable Internet providers block use of port 25 outside of
their own e-mail server. That is, if you use Yahoo! DSL, then the only
outside machine they allow you to use for SMTP is the mail.yahoo.com
server.

The best solution I've found is looking for a secure connection to the
*.edu server. Using an SSL connection for SMTP typically uses Port
465, and because it require authentication, few ISPs block its use.
Check with your e-mail provider for available SSL connection settings.

If they don't offer any SSL connection, you can use the ISP's
connection from home.

The reason for blocking standard SMTP ports is to reduce spam and
other misuses of e-mail -- traditional SMTP requires very little
authentication.

Port 587 is usually the preferred port to use for submissions, and you
should be authenticating to get that through. Try

smtp.xxx.edu:587/tls/user=litd99

or

smtp.xxx.edu:587/user=litd99

The user= will cause it to ask you for your password and then to
authenticate to the smtp server.
