How to solve error messages on Outlook Express

[VIV]

I just installed sympatico internet kit on my computer. I am now connected.
However I am unable to send messages from Outlook Express. I keep getting
error messages as follows: "Unable to establish a SSL connection with the
server. Account: 'pophm.sympatico.ca', Server: 'smtphm.sympatico.ca',
Protocol: SMTP, Server Response: '454 TLS not available due to temporary
reason', Port: 25, Secure(SSL): Yes, Server Error: 454, Error Number:
0x800CCC7F"

Hi VIV,
If you're getting an error along the lines of: Unable to establish a SSL
connection with the server. Account: '(e-mail address removed)',Server:
'mail.isite.net', Protocol: SMTP, Server Response: '454 TLS not available
due to temporary reason', Port: 25, Secure(SSL): Yes, Server Error: 454,
Error Number: 0x800CCC7F ...then it may be a problem with antivirus software
scanning outgoing mail. This is a known problem with Norton Antivirus and
may also happen with other antivirus applications. Try disabling the
scanning of outgoing mail and see if the problem is resolved.
