Postfix stable release 3.4.8

[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.4.8.html]

Fixed in Postfix 3.4:

* Fix for an Exim interoperability problem when postscreen after-220
checks are enabled. Bug introduced in Postfix 3.4: the code
that detected "PIPELINING after BDAT" looked at the wrong
variable. The warning now says "BDAT without valid RCPT", and
the error is no longer treated as a command PIPELINING error,
thus allowing mail to be delivered. Meanwhile, Exim has been
fixed to stop sending BDAT commands when postscreen rejects all
RCPT commands.

* Usability bug, introduced in Postfix 3.4: the parser for
key/certificate chain files rejected inputs that contain an EC
PARAMETERS object. While this is technically correct (the
documentation says what types are allowed) this is surprising
behavior because the legacy cert/key parameters will accept
such inputs. For now, the parser skips object types that it
does not know about for usability, and logs a warning because
ignoring inputs is not kosher.

* Bug introduced in Postfix 2.8: don't gratuitously enable all
after-220 tests when only one such test is enabled. This made
selective tests impossible with 'good' clients. This will be
fixed in older Postfix versions at some later time.
