Qmail patches/add-ons

• qbiff-onetty-patch. With this patch, qbiff (part of qmail) only writes to the terminal with the most recent access time instead of writing to all terminals. It also truncates the first line to 78 characters.
• qmail-smtpd-571-patch. With this patch, qmail-smtpd responds with
  571 sorry, your envelope sender is in my badmailfrom list (#5.7.1)
  instead of
  553 sorry, your envelope sender is in my badmailfrom list (#5.7.1)
  when mail is received that matches something in badmailfrom. It also emits the error message after the "Mail from:" line instead of "Rcpt to:". This stops fetchmail from whining about the 553 error code.
• splogger-nosyslog. Replacement for qmail's splogger that doesn't use syslog as extensively as splogger but writes to a logfile directly. It fdatasync's every 15 seconds, and reopens the logfile when it receives a SIGHUP (very useful for automatic logfile rotation programs).
• ezmlm-moderate, a shell script to restrict the posting of messages to a list. Insert a line like
  |/usr/local/bin/ezmlm-moderate mylistdir
  before the other lines in .qmail-mylist. Create a file mylistdir/moderators, and optionally a file mylistdir/text/moderated with some text explaining the situation (it will be included in bounce messages).
