The ProblemYou want to set up an SMTP server to let you send mail out of your local instance of CQ5 author.
The SolutionSet up a GMail account (or use your own if you feel comfortable where you are storing the information).
1. Go to the Felix Console
2. Scroll down and click to edit the Day CQ Mail Service OSGi config.
3. Enter the following details:
SMTP Server Host - smtp.gmail.com
SMTP Server Port - 465
SMTP User - your username (i.e. email@example.com)
SMTP Password - your password
From Address - your email
SMTP Use SSL - true
4. Hit Save
5. Run a user through a workflow containing a group of which you are a member, or send out a newsletter to a group which you are a part of.
You should receive the email in your inbox.
It is worth noting that for production environments, you should set up a production grade SMTP service rather than use GMail.
