Overview

Define: sendmail::mc::enhdnsbl

Manage enhanced DNS blacklist entries

Parameters:

blacklist

The DNS name to query the blacklist.

allow_temporary_failure

Sample Usage:

sendmail::mc::enhdnsbl { 'dialups.mail-abuse.org':
  reject_message          => '"550 dial-up site refused"',
  allow_temporary_failure => true,
  lookup_result           => '127.0.0.3.',
}

Parameters:

  • blacklist (String) (defaults to: $title)
  • allow_temporary_failure (Boolean) (defaults to: false)
  • reject_message (Optional[String]) (defaults to: undef)
  • lookup_result (Optional[String]) (defaults to: undef)
