I've discovered a cool thing to do with e-mail filters in Fastmail. If you include a "secret word" in your subject line, or use e-mail+secretword@fastmail.fm as the recipient, it will bypass all filters - ie it will definately get through to me.
I now designate my secret word to be batchcakes - but replace the a with an i where it most counts. This refers only to my public address that I tend to send mails out to friends with by mistake instead of my personal address.
