"notification bot for quoting me in a post" there is no official bot for quoting on Bitcointalk, if you are a member of Maggiodormo, check if you have received any PMs from it. If you have received PMs on Bitcointalk but no email, there is a huge chance that the mail might've gone to your spam folder. Also, try to use Maggiodormo with Telegram instead of Bitcointalk PMs. It's an unnecessary burden for Bitcointalk's servers and database. If you have problems with the bot not sending you notifications, you have to contact Piggy. And check here
If it still not there, then there must be problem on forum's email provider.
Try to check your forum mail settings, both your email address and notification preferences. Also, what mail service/client you are using? If you are using something other than GMail or any well-known provider, that might be the issue. They might've blocked Bitcointalk's mail system/addresses.
