Another way of achieving authentication for email is to implement and
use S/MIME or PGP. I'm not sure either that or "import ... /mail" solves
the computational cost of spam if the bad guys create invalid signatures,
but it does make a white-list filter more effective.
Any volunteers to implement S/MIME for Plan 9? A couple of us here at
Bell Labs have worked on it off and on, but there aren't enough free
hands here to get it done promptly. Step one is to implement CMS (also
known as PKCS#7 or rfc2315) starting from the ASN.1 goo in
/sys/src/libsec/port/x509.c or, if you prefer, by porting an ASN.1
compiler.
By the way, I've happily used PGP for many years but decided that S/MIME
was more likely to catch on because it is already moderately well
supported by default in Outlook and Netscape/Mozilla.
