[sdiy] spoof warning on emails from synth-diy

[Ben Stuyts]

Well, if there is DMARC info, then the From: address should be properly munged and a Reply-To: will be added. You would see “From: Name Via Synth-DIY <synth-diy at synth-diy.org <mailto:synth-diy at synth-diy.org>>”. I did a quick check the settings didn’t change/fall over for the mailing list, but they seem to be OK.

Last week the name server infra-structure of the synth-diy.org <http://synth-diy.org/> hosting firm has been severely DDoS’ed, perhaps there are still some loose ends. I’ll go test some more...

Specifically, the fact that the sdiy mailer uses my email address as the "From" header. There might be a better header that doesn't necessarily "impersonate" the original sender. For example, maybe Original-From would be a better choice here, and meanwhile use the sdiy email address as the From address.
