Postfix 2.0 patch 20 available

Postfix 2.0 patch 20 fixes a few minor problems that are also fixed
in the official Postfix 2.1 release and in Postfix 2.2 snapshots.

After this patch, support for Postfix 2.0 will dry up as more effort
is put into updating Postfix 2.1 and improving Postfix 2.2.

- The postdrop mail submission command could die with SIGHUP and
abort mail submission.  This was observed with mail from cron jobs.

- The MySQL client aborted with complaints about multiple attempts
to register the same lookup table. This was observed in the proxymap
daemon.

- As a workaround for agressive SMTP command pipelining clients,
the Postfix SMTP server now allows SMTP clients to overshoot the
SMTP server recipient limit without triggering the server hard
error limit, as long as the number of excess recipients stays within
a hard-coded overshoot limit of 1000. If you have such clients then
you also need to specify "smtpd_error_sleep_time = 0" or else
performance will be poor.

- The LMTP client attempted to reuse a connection after timeout,
causing protocol synchronization errors.

- The trivial-rewrite server could core dump after temporary table
lookup failure.  This was not observed in Postfix 2.0.
