I was having quite the time successfully configuring the AVG admin console to send email notifications because it does not support email addresses that require SSL, and my company only has SSL-based email addresses. AVG support could not help me, but, I found a solution!
Use JangoSMTP, which has a free version that allows up to 200 outgoing emails per month (more than enough for this purpose). After creating the account, I used the default settings, which are:
SMTP server: relay.jangosmtp.net
username: (your Jango username by itself, not an email address).
That did it for me! I just thought I'd post this solution here so others don't have to go through the pain I went through on this.
