Import Postfix 2.8.7. Changes since version 2.8.6:

Browse Source 
Postfix stable release 2.8.7 is available. This contains a workaround for
a problem that is fixed in Postfix 2.9.
- The postscreen daemon, which is not enabled by default, sent non-compliant
  SMTP responses (220- followed by 421) when it could not give a connection
  to a real smtpd process. These responses caused some remote SMTP clients
  to return mail as undeliverable.

  The workaround is to hang up after sending 220- without sending the
  421 "sorry" reply; this is harmless.

Workaround: postscreen sent non-compliant SMTP responses
(220- followed by 421) when it could not give a connection
to a real smtpd process, causing some remote SMTP clients
to bounce mail. The workaround is to hang up without sending
the 421 reply (which is harmless); the complete fix involves
too much change for a stable release. Problem reported by
Ralf Hildebrandt. File: postscreen/postscreen_send.c.
