# Norton Antivirus causes email sending problems

The outgoing email scanning function in Norton Antivirus is usually turned on by default. Individuals who use <span class="caps">NAV</span> should be aware that the scan does not support <span class="caps">SSL</span>. Please do not be alarmed if the following message occurs:

Unable to establish a <span class="caps">SSL</span> connection with the server. Account: ‘<span class="caps">SSCNET</span>’, Server: ‘mail.ucla.edu’, Protocol: <span class="caps">SMTP</span>, Server Response: ‘454 <span class="caps">TLS</span> not available due to temporary reason’, Port: 25, Secure(<span class="caps">SSL</span>): Yes, Server Error: 454, Error Number: 0×800CCC7F.

Simply turn off the outbound scanning feature and the email client using <span class="caps">SSL</span> can send mail again. See <span class="caps">NAV</span> help files to disable scanning feature (instructions will vary based on different versions).

<span class="caps">UCLA</span> pays for Sophos, so that is what I use. However, Notre Dame uses Norton, so here are some instructions from its site:
