10172 Thu Jan 06 10:46:54 GMT 1983 eric split up FULLSMTP flag -- now have "X" (M_XDOT, use hidden dot algorithm), "p" (M_FROMPATH, use reverse-path in MAIL FROM:<> command), and "L" (M_LIMITS, enforce SMTP line limits). I would like to change the format of the mail defn one more time to make named fields so that it would be more extensible.
