This is not a practical comment, but... I am amazed Amazon is checking
the header From instead of the header Sender and envelope sender... and
recommending breaking standards to get around what they are doing. They
not only break mailing lists but the types of forwarding that preserve
the original From header. RFC 2822:

   The "From:" field specifies the author(s) of the message,
   that is, the mailbox(es) of the person(s) or system(s) responsible
   for the writing of the message.  The "Sender:" field specifies the
   mailbox of the agent responsible for the actual transmission of the

The latter, and the envelope sender, is what they should care about.

All right, enough, back to real life where you just have to deal with
crazy stuff you can't control...
