Regarding events that occur with RFC violating addressesThe email address of the already registered lead violates the RFC.
If you send an email to that lead without making corrections, there is a possibility that some of the emails sent will contain system errors.
We recommend that you correct your information or remove yourself from the distribution list before sending the email.
■ Cases of occurrence that have already been confirmed
If you send an email while the distribution list contains an incomplete email address (an email address that violates the specifications stipulated by the international standard RFC (Request for Comments)), the delivery results for some leads will result in a system error.
If a system error occurs, please remove the lead from being sent or correct the address and resend the email.
We also recommend checking the lead's email address before sending.
