P.S.: 26 new "misdirected" bounces while I typed this article.

You need to use self-signing SRS or old SES to discard those
misdirected bounces. I've gotten 200 since yesterday, but I had
to grep the log to count them. Old SES doesn't compute a body hash,
and is useful as an improvement over self-signed SRS for blocking
[New SES is an alternative to DKIM where you query the sender to validate
a hash code instead of fetching a public key and validating a signed
hash code. Unlike DKIM, it can stop most forgeries before SMTP DATA.
Like DKIM, it suffers from body hash limitations.]
