Asahi Net : Blocking Receipt of Mail with Invalid Sender's Address

13th Dec. 2004. Blocking Receipt of Mail with Invalid Sender's Address

The domain portion of the sender's mail address is inspected at the time of receipt and the mail is blocked if the domain does not exist. This feature is intended to prevent anonymous and/or malicious mail from reaching the member's mailbox.

Conditions

ab4t-ash@asahi-net.or.jp The domain exists and so receipt (and sending) is possible.
ab4t-ash@a-sa-hi-net.or.jp The domain does not exist and so receipt (and sending) is not possible.
ab4t-ash@asahinet The domain does not exist and so receipt (and sending) is not possible.
ab4t-ash@ No domain is present and so receipt (and sending) is not possible.

Important
When sending to an email address with a valid domain and getting an error message, please check the settings of your own email software to make sure the domain name of your own email address is correct.
