You don't. You allow the sender to discover when it's been blocked. After
all, email is sent because the sender wants to tell the recipient
something, not because the recipient wants it.
In the other case, where the recipient has asked for an email to be sent,
they'll know it's missing because it isn't in their mailbox.
How do you inform the sender? Well, you reject the email at SMTP time. If
the sender is using an RFC compliant email system, they'll get a
notification (if they want it). If they're not, then they're probably a
spammer.
