Subject: [Exim] Warning: spammers abusing vacation autoresponders
I'm seeing more and more spam come in, where the spammer used a fake
sender and abused a vacation-style auto-responder. Mostly, I doubt that
Exim has been involved in this.

Since the spammer doesn't care about how many mails they send,
restrictions such as "once" don't help. Setting text or file does ...
unless it's expanded and includes something like $message_body.

Mr Hazel Sir, could you please add a throttling feature? No more than N
mails per day from a responder? 100 default, option to change?

Or are there people who so desperately need those auto-responses to get
out, that it's worth having a route-list-style or retry-style option for
controlling maximum autoresponder rates?

Or is there a better way of preventing issues with $message_body being
returned?
