disable badh checks ?

[lists at sbt.net.au]

I have a amavisd-new-2.12.1 with Postfix/Dovecot since like forever,  all
working well

I'm thinking of disabling bad header checks (seems surplus today..?)

mails with badh get delivered to 'badh' in basket in Maildir

what's the proper way to disable badh check ?

if I delete badh sub folder in Maildir - will that then simply flag badh
and, deliver to main inbox, will that do ?

is there a way to generate a test badh mail to check/test my setup ?

thanks for any pointers!

# grep badh /etc/amavisd/amavisd.conf

  warnbadhsender   => 1,
@addr_extension_bad_header_maps = ('badh');
# $warnbadhsender,
# $warnvirusrecip, $warnbannedrecip, $warnbadhrecip, (or @warn*recip_maps)
