Settings of the Blogs module can be done in Site Manager -> Settings -> Content -> Blogs. The following settings are available:

 

•Blog unsubscription URL - URL of a page on which the Blog post unsubscription web part is placed; this is a special web part used for handling unsubscriptions from receiving notifications about new blog posts

•Send blog e-mails from - e-mail address that will be used as the Sender ('From') address of notification e-mails

•Enable blog post trackbacks - If checked, specified blog posts are pinged after the new blog post is saved; turn off this setting if you are creating your site on the production server to avoid creating trackbacks to your production server

•Use external service for trackbacks - indicates if the external Scheduler Windows service should be used to process scheduled tasks which handle trackbacks.
