Hi Tom, You write that you're using Qmail. If you'd like to implement DKIM signing for your outgoing mail (for possibly better deliverability and also so that you could verify incoming mail and be sure that it's not your own by verifying the DKIM signature), then perhaps you're interested in what I've worked on: I didn't want to patch Qmail for DKIM support, so I took an existing, older script that works as a wrapper for qmail-remote and improved it. It can now also add hashcash stamps (which may or may not actually be useful, but in any case doesn't hurt me since I've got plenty CPU time for it), and checks whether the mail to be sent is a bounce for a likely spam, in which case it diverts it locally to avoid sending backscatter. This has only been tested by me so far, so YMMV.. tell me if you run into problems.
https://github.com/pflanze/better-qmail-remote I've just made a release v0.1, you can verify its signature with `git tag -v v0_1` using the key: http://christianjaeger.ch/pgpkey-A54A-1D7C-A1F9-4C86-6AC8--1A1F-0FA5-B211-04ED-B072.asc Cheers, Christian.
