This technique works great to keep spam out of your mailbox.Inline rejection is a little dangerous for mailing lists
And for anyone else who doesn't feel like jumping through your hoops.
Providing a telephone number in the bounce is an effective way to deal with false positives.
Only if you assume that everyone who writes to you is so desperate to send you mail that they are willing to make what may be an international call in the middle of the night. I have not found that to be a very realistic assumption.
