If you can not receive mail from this service, please confirm the following contents.

■　Things to set up

Please set "Junk mail filter" "spoof mail reception prevention setting" so that you can receive mail of domain "arkray.co.jp".

* Especially at au's mobile phone address (ezweb.ne.jp), even if it is blocked by a filter, there is no notification at the sender side, so we can not confirm the arrival availability at our company. Please be sure to set up.

* Even with the e-mail address for PC, it may be automatically sorted into spam mail. In the case of e-mail not arrived, please confirm "spam mail BOX" etc.
