Little did I realize when I became a committer I would be the recipient of 200+ emails daily. Between my optional mailing lists, coupled with internal FreeBSD messages, cvs-commit control messages, and gnats notifications, I found my Inbox filled up, quickly.
I learned to use procmail. I highly recommend it. Apply some simple recipes, and voila, messages can be auto-filed for reference, leaving the Inbox a lot less cluttered.
Even if you don’t get a huge volume of email, check it out anyway!
