Postfix version 19991231 patchlevel 03 fixes low-priority defects
and provides workarounds for unusual conditions.

- Workaround to prevent one site with a huge backlog from blocking
  all other deliveries. This is controlled by a new configuration
  parameter qmgr_site_hog_factor (default: 90 percent) that limits
  how much in-memory queue manager resources a site can claim.

- Workarounds for the most likely problems that will happen when
  running the Postfix queue on top of NFS.

- The SMTP server did not look in the relocated table and would
  report "User unknown" rather than letting the mail bounce the
  way it is supposed to be.

- When requested to extract recipients from message headers, Postfix
  now insists that no message header exceeds the header size limit.
  This prevents Postfix from inadvertently disclosing Bcc: addresses.

postfix-19991231-patch03 is about 1500 lines. This is too large
for distribution via mail. The patch and a fully-patched version
of the source code are being made available via the usual FTP
