I think there is still more taint issues in 4.93. There is an issue with
unix socket responses too. FreeBSD operating system.

2020-02-24 10:01:32 1j6FEi-0009ku-RP Taint mismatch, Ustrncpy:
ip_unixsocket 518

   deny    malware    = */defer_ok
           condition  = ${if def:malware_name {true}{false}}
           message    = Message content has virus signature ($malware_name).


and

   deny   spam       = nobody:true/defer_ok
           condition  = ${if def:spam_report {true}{false}}
           add_header = :at_start:X-Spam-Status: $spam_report
           message    = Message content has high spam score
