I gave up getting annoyed over Easter. But if I were to be annoyed, it might be at receiving an from someone, in response to my email to them, that reads like the following:

I apologize for this automatic reply to your email. To control spam, I now allow incoming messages only from senders I have approved beforehand. If you would like to be added to my list of approved senders, please fill out the short request form (see link below). Once I approve you, I will receive your original message in my inbox. You do not need to resend your message. I apologize for this one-time inconvenience. Click the link below to fill out the request.

I'll pass on being added to your list of "approved senders".
