[from "book-of-the-month club", a time-honored mail-order-marketing
technique in the U.S.] A mythical club which users of sendmail(8)
(the Unix mail daemon) belong to; this was coined on the Usenet
newsgroup comp.security.unix at a time when sendmail security holes,
which allowed outside {cracker}s access to the system, were being
uncovered at an alarming rate, forcing sysadmins to update very
often. Also, more completely, fatal security bug-of-the-month club.
