Troubleshooting Email
If you are having problems with your email notifications, you can use the Movable Type comment notifications to test your setup. If they don't work, MT-Notifier won't work either.
If you are creating either blog- or category-level subscriptions, and your installation requires confirmations, make sure that you have specified a default email address on the system-level blog settings.
If you haven't, then there is no "sender address" to use on those confirmation emails, and nothing will be sent! You can also verify that this is a problem by checking your activity log for an error.
Missing Slashes in URL
If the URL is missing a slash, specifically between the Movable Type directory and the "plugins" directory, check the CGIPath setting in your configuration file to make sure it has a trailing slash (a slash at the end).
Incorrect Script Name in URL
This final email tip is a bit obscure. If you find that your messages lose a dot (for instance, mt-notifier.cgi turns into mt-notifiercgi), check the version of Mail::SendMail on your server. Version 0.78 has been shown to have this problem. Version 0.79 solves it. (Thanks to Stanford ITSS.)

Comments
Hi! I installed MT Notifier on my MT installation (latest version from the site; MT 3.2) and I can't get it to send notifications. I just tested the comment notification functionality and that works, so MT is sending out emails. I'm not having any subscribers from the public blog, only ones that I manually added in via the MT interface (where I click on "Notifications" and add them there). I checked to make sure the files have the right permissions. Under the configuration option in the Plugins list on the MT interface, I chose do not send confirmation messages (since I'm adding them in myself, I don't need a confirmation mail), and I chose the "do not submit notifications to deliver queue" (although I also tested it with the other option) - no go. Since the plugin appears on the MT menu and I can work with it there, the plugin is installed and working (in some form). I also tried your suggestions here, like setting the default from email address in mt-config.cgi, etc, and it doesn't help. I just don't know what to do so that it has to send e-mails. What do you recommend?

Hi Morgan - Unless I'm mistaken, it sounds like you are adding notifications through the Movable Type option. Those don't work with MT-Notifier.
You can allow users to subscribe via a checkbox on the comment form, a standalone form or you can add subscribers using the itemset action menu, but not the Notifications.

Hi Chad - Yes, I think that's what the problem is - I probably saw the "Notifications" menu and used that. I don't understand "itemset action menu" - it sounds like it's an option within the MT user interface, but I can't find it. What should I click on to find the option to list people? Thank you so much!

Hello,
I recently upgraded to MT 4.01 and MT-Notifier 4.0.2. I previously used MT and MT-Notifier 2.x with success.
I followed the upgrade instructions, deleting all the old Notifier files and folders, and the upgrade appeared to go smoothly. I added a blog-level subscription using the itemset pull-down menu. I checked that there is a system email address. But when I post to the blog, no emails are received. There is also no sign of the notification in MT's activity log. There is, however, this in my server logs:
usage: /usr/lib/sendmail [-f] [-t] [-s] [-T] [-v] [address ...]
I don't know what it means. Maybe nothing. Since I've previously used Notifier successfully, there shouldn't be anything wrong with sendmail, right?
Help?
