How to avoid bogus bounces.

In January, I mentioned that bounce messages that were not generated in response to messages I sent are discarded automatically.The technique for doing this goes as follows: My mutt installation is configured to use envelope sender addresses (MAIL FROM, that is) different from my normal e-mail address for anything but list mail. Bounces sent to my normal e-mail address are discarded by my mail filter configuration — these are the fake ones. Bounces directed to the specific MAIL FROM address I use, however, pass the filter, and end up in my inbox.The sytem works fairly well for me, but of course requires rather fine-grained control over the different addresses to go into MAIL FROM (for machine answers) and the From header (for human answers).(Maybe I should attempt to patent this?)
