Postfix HELO_Restrictions

For fighting against SPAM with Postfix helo_restrictions it would be nice to have a Input-Field.

The Option "check_helo_access hash:/etc/postfix/helo_access" in smtpd_helo_restrictions must not be databaseintegrated.

/etc/postfix/main.cf smtpd_helo_required = yes smtpd_helo_restrictions = permit_mynetworks, permit_sasl_authenticated, check_helo_access hash:/etc/postfix/helo_access,reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, reject_unknown_helo_hostname
