Log Message:
mail/postfix: update to 3.3.2

Changes for all supported stable releases:

  * Support for OpenSSL 1.1.1, and support for TLSv1.3-specific
    features.

      - Updated Postfix TLS documentation examples for TLSv1.3. See
        FORWARD_SECRECY_README.

      - New TLSv1.3-specific attributes in Postfix logging and in
        Postfix "Received:" message headers: key exchange, server
        signature, client signature.

      - New option to selectively disable TLSv1.3 in *_tls_protocols
        settings.

      - New server-side support to avoid issuing multiple session
        tickets.

      - New support to allow OpenSSL >= 1.1.0 run-time micro version
        bumps without logging Postfix warnings about library version
        mismatches.

Fixed in all stable releases:

  * Bugfix: smtpd_discard_ehlo_keywords could not disable "SMTPUTF8",
    because some lookup table was using "EHLO_MASK_SMTPUTF8" instead.

  * Bugfix: minor memory leak in DANE support when minting issuer
    certs. This affects a tiny minority of use cases.

Fixed in Postfix 3.3.2:

  * Bugfix: the Postfix build did not abort if the m4 command was
    not installed, resulting in a broken postconf command.
