Cannot send e-mail

[M Mordkovych]

Hi All!
Cannot send e-mail. Error is :

Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: 'mci hi speed', Server: 'smtpauth.mcihispeed.net',
Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC0F

I can send e-mail on other machine on the network.

See what happens when you disable e-mail scanning in your anti-virus
program, and in your anti-spam program, if you use one, or anything else
that intercepts and interrogates the mail traffic.

In addition to Vanguard's advice, make sure you're properly authenticating
the SMTP server.
