Not receiving email when new thread/post happens

[snakes1100]

The best way to determine why emails are not being sent is to view the email log from the server, if this is a dedicated server, depending on email program, you can find the email log in /var/log/maillog

If this is a vhost server, you should ask your host.

You can use the admincp --> maintenance --> diagnostics --> email and send your self a email.
