	mail_version = 3.7.3
perldoc Mail::Milter::Authentication | grep version
    version 3.20221006
perldoc Mail::AuthenticationResults | grep version
    version 2.20210915

where authentication_milter runs in SMTP mode,

...
"connection" : "inet:13001@127.0.0.1",
"protocol"  : "smtp",
"smtp" : {
    "sock_type"      : "inet",
    "sock_host"      : "127.0.0.1",
    "sock_port"      : "13002",
...

i notice in logs lots of these "unexpected token" errors,

where,

https://github.com/fastmail/authentication_milter/blob/master/lib/Mail/Milter/Authentication/Handler/Sanitize.pm#L129

seems to be involved.

Known issue?
Or, what add'l info/tests are needed here to track it down?

In order to know if this is a known issue, It would be useful if you could provide a sample of the authentication header that is actually been parsed and it is trggering this error.

An existing Authentication-Results header could not be parsed, It will be present in the resulting message with a modified header name.
I think the best change here is to update the logging to show the header that could not be parsed.
