I can’t seem to get mail notifications to work when a page gets changed.
I have also installed a plug in to send mail over smtp, and on the plug in the email test works, but my test user is still not getting emails about page edits on the pages they asked for.
You could try to change the “from” email address (or your default site admin email) to a gmail account or something other than an official department account. Sometimes, mail servers will block email that appears to come from an official address but which is actually sent from the intranet server.
Sorry, yes I am using the HT Notify plug-in and a user has selected pages they want to be notified about when they are changed. I have then changed a couple of the selected pages and they received no email.
