on your system.
A bot would not normally be sending this type of mail to you, but would be sending stuff out from your machine to other places.

What you appear to have done is get yourself on a nasty email list and you will continue to get this type of mail until they get bored of sending it or you change your email.

Assuming you are using Apple Mail, then build yourself a spam rule that will drop these emails where they belong. You can do that with any email client.
