Log Message:
Update postfix to 3.1.4.

Postfix stable release 3.1.4 is available, as well as legacy releases
3.0.8 and 2.11.9. There will be no further updates for Postfix 2.10.

Fixed with Postfix 3.1.4, 3.0.8, and 2.11.9:

  * The postscreen daemon did not merge the client test status
    information for concurrent sessions from the same IP address.
    Thus, after one session recorded its successful tests in the
    postscreen cache, a concurrent session from that same IP address
    that passed fewer tests could later "wipe out" some of that
    progress in the postscreen cache. The fix has proven itself for
    five months in the development release, and should be safe to
    use in the stable releases.

  * The Postfix SMTP server falsely rejected a sender address when
    validating a sender address with "smtpd_reject_unlisted_recipient
    = yes" or with "reject_unlisted_sender". Cause: the address
    validation code did not query sender_canonical_maps.

  * The virtual delivery agent did not detect failure to skip to
    the end of a mailbox file, so that mail would be delivered to
    the beginning of the file. This could happen when a mailbox
    file was already larger than the virtual mailbox size limit.

  * The postsuper command logged an incorrect rename operation count
    after creating a missing directory.

Fixed with Postfix 3.1.4 and 3.0.8:

  * The Postfix SMTP server falsely rejected mail when a sender-dependent
    "error" transport was configured. Cause: the SMTP server address
    validation code was not updated when the
    sender_dependent_default_transport_maps feature was introduced.
    The fix has proven itself for six months in the development
    release, and should be safe to use in the stable releases.
    Unfortunately, Postfix 2.11 is too different to benefit from
    the same fix.

  * The Postfix SMTP server falsely rejected an SMTPUTF8 sender
    address, when "smtpd_delay_reject = no".

Fixed with Postfix 3.1.4:

  * The "postfix tls deploy-server-cert" command used the wrong
    certificate and key file. This was caused by a cut-and-paste
    error in the postfix-tls-script file.
