From https://www.fehcom.de/qmail/smtpauth.html#PATCHES Generic SMTP authentication for qmail-smtpd and qmail-remote. Complies to RFC 3848 and RFC 4409. * Provides now CRAM-MD5 authentication for qmail-remote as well. * Fine tuning of SMTPAUTH annoncements for qmail-smtpd and SUBMISSION support. * Sender based authentication according to 'Mail From:' and authenticated smarthost relaying for qmail-remote. * Fixed bug (0.8.2): qmail-smtpd secretly allows auth even when disabled! (tx Chris P.) * Fixed AMD64 bug for MD5 (0.8.3) and small others (tx Alan P.)
