Someone is mailbombing me!

Consider them a spammer, and set up a filtering rule, killing offending email upon arrival.

Consider complaining to their ISP as well, usually abuse@domain.com is the address for complaints. If that doesn't work, try postmaster@domain.com. Of course, domain.com shouldn't be put in literally, it should be substituted with the offending ISP's domain name.

Please contact support@binary.net if you have any questions.
