Dead letter bin / black hole email address

[email protected]
The good old bitbucket, just what you're looking for.

You could use a service such as Mailinator, where you can send an email to addresses such as:

{any-valid-string}@mailinator.com

The email will be deleted after a few hours. However, in theory, the email can be read by anyone who knows the {any-valid-string} you pick, and there are some other caveats in the FAQ. And (as for any server) you would have to assume the Mailinator servers are up and running when needed; otherwise you may get a bounce-back.

How much (if any) control do you have over your e-mail addresses?

If you have none, then the simplest solution might be to set up a hotmail (or similar) account and effectively abandon it.

If you have a lot, then you can add an address to your domain ([email protected]) this will then be valid and not generate a bounce. Depending on your mail server you should be able to just delete mails going to this account.

If you want to go this route then asking the question at Server Fault might get you better responses.

I would have posted this a comment, but it got rather long winded

If you do choose to go the create-your-own route, the following .procmailrc script should delete all mail coming to it:

VERBOSE=off
LOGFILE=/dev/null

# delete all mail

:0
/dev/null
