Hi,

I need to have the following on a user (external entity):
Automatic subscription for a course, seminaries .
When he receive a mail before 1 november 09:00 AM there should be an automatic reply send with a message and the mail is rejected and the person who send the mail is not subscribed.
After 1 november 09:00 AM the messages are accepted and the person who send the mail is subscribed.
I hope you understand my question.

Is it possible to do this via rules and How can I do this?

Thanks

Herman
