Once you have Graffiti set up and you are posting content you’ll probably want to be notified by Graffiti when new user comments are made or if someone uses your contact form. So, one of the first things you’ll want to do is make sure your e-mail settings are configured properly.
Log into Graffiti as a site administrator and click on the Site Options tab and then click on e-mail settings.
Once you are on the e-mail tab you’ll want to configure the settings. Your ISP should have help on how to configure applications to send e-mail so you may need to contact them.
After you have updated the settings from your ISP you’ll want to make sure the from address is set appropriately and that you’ve tested via the test settings field.
More information can be found here about the e-mails that are sent by default, but Graffiti plug-ins may also be taking advantage of e-mail settings that are configured as well. For example: with the blog extensions authors will get notifications for trackbacks that are posted just like comments.
