Meanwhile, countermeasures against spam are indispensable because e-mail tends to trigger illegal invasions. Spam countermeasures conventionally used check sender MTAs, such as S25R for judging whether the FQDN of the sender MTA is like a mail server or user terminal, gray listing for checking the operation of the sender MTA after a temporary error, or sender MTA is on blacklist. However, due to the leakage of ID / password, spam sent from an authorized server such as a provider's MTA is increasing. Therefore, from May 2017 the inspection of the sender's mail address was strengthened.
