Postfix 3.7.4 (2023-01-22)

  * Workaround: with OpenSSL 3 and later always turn on
    SSL_OP_IGNORE_UNEXPECTED_EOF, to avoid warning messages and missed
    opportunities for TLS session reuse. This is safe because the SMTP
    protocol implements application-level framing, and is therefore not
    affected by TLS truncation attacks. Fix by Viktor Dukhovni.

  * Workaround: OpenSSL 3.x EVP_get_digestbyname() can return
    lazily-bound handles for digest implementations. In sufficiently
    hostile configurations, Postfix could mistakenly believe that a digest
    algorithm is available, and fail when it is not. A similar workaround
    may be needed for EVP_get_cipherbyname(). Fix by Viktor Dukhovni.

  * Bugfix (bug introduced in Postfix 2.11): the checkok() macro in
    tls/tls_fprint.c evaluated its argument unconditionally; it should
    evaluate the argument only if there was no prior error. Found during
    code review.

  * Bugfix (bug introduced in Postfix 2.8): postscreen died with a
    segmentation violation when postscreen_dnsbl_threshold < 1. It
    should reject such input with a fatal error instead. Discovered by
    Benny Pedersen.

  * Bitrot: fixes for linker warnings from newer Darwin (MacOS)
    versions. Viktor Dukhovni.

  * Portability: Linux 6 support.

  * Added missing documentation that cidr:, pcre: and regexp: tables
    support inline specification only in Postfix 3.7 and later.
