Incompatibility with Postfix 2.5.3

When a mailbox file is not owned by its recipient, the local and
virtual delivery agents now log a warning and defer delivery.
Specify "strict_mailbox_ownership = no" to ignore such ownership


        Bugfix: null-terminate CN comment string after sanitization.
        File: smtpd/smtpd.c.


        Workaround: avoid "bad address pattern" errors with non-address
        patterns in namadr_list_match() calls. File: util/match_ops.c.


        Bugfix (introduced 20080207): "cleanup -v" panic because
        the new "SMTP reply" request flag did not have a printable
        name. File: global/cleanup_strflags.c.

        Cleanup: using "Before-queue content filter", RFC3848
        information was not added to the headers. Carlos Velasco.
        File smtpd/smtpd.c.


        Cleanup: a poorly-implemented integer overflow check for
        TCP MSS calculation had the unexpected effect that people
        broke Postfix on LP64 systems while attempting to silence
        a compiler warning.  File: util/vstream_tweak.c.


        Paranoia: defer delivery when a mailbox file is not owned
        by the recipient. Requested by Sebastian Krahmer, SuSE.
        Specify "strict_mailbox_ownership=no" to ignore ownership
        discrepancies.  Files: local/mailbox.c, virtual/mailbox.c.
