I think it is more of an SMTPAuth problem. Either SMTPAuth is not enabled or
the authentication method is not set to PLAIN.

Check the option in advanced settings for:
"Log onto incoming mail server before sending mail"
(make sure it is checked)

I think you may need to be looking at a newer version of Outlook if it's
even attempting SSLv3. Anything older than 2010 is pretty much useless these
days, and you really have to dumb down a server for 2011 (Mac) to work.
