It then makes sense to add these to violations.ignore.d/ssh:

  ^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ sshd\[[[:digit:]]+\]: error: PAM: User not known to the underlying authentication module for illegal user [[:alnum:]]+ from [_.[:alnum:]-]+$
  ^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ sshd\[[[:digit:]]+\]: I(llegal|nvalid) user [-_.[:alnum:]]+ from (::ffff:)?[.[:digit:]]+$
  ^\w{3} [ :[:digit:]]{11} [._[:alnum:]-]+ sshd\[[[:digit:]]+\]: Failed (keyboard-interactive/pam|password) for i(llegal|nvalid) user [[:alnum:]]+ from (::ffff:)?[.[:digit:]]+ port [[:digit:]]{1,5} ssh2$

Please do not send copies of list mail to me; I read the list!
