FAQ concerning email (Gmail)

  1. For email to arrive with the old system (DEEPMail), it will not arrive with the new system (Gmail).
  2. When I have logged in to Keio mail (Gmail), normal Gmail service opens.
  3. I have forwarded emails received by Keio mail to an email address of a cell phone, but recently I do not receive these emails on the cell phone.
  4. When I have logged in to Keio mail (Gmail), "Contains a redirect loop on this web site." was displayed.

(Q1) For email to arrive with the old system (DEEPMail), it will not arrive with the new system (Gmail).
(A1) With the new system (Gmail), the email can be sorted into the Spam folder. Please check to find out if the email is included in "Spam". Please check to find out if the email is included in "All Mail". If you do not want to filter all spam mail, please see Method of not filtering all spam mail.

(Q2) When I have logged in to Keio mail (Gmail), normal Gmail service opens.
(A2) Log out of Gmail, and log in to Keio mail once more. You can switch between normal Gmail service and Keio mail on your Web browser. For details, see "Account switching operation method". The reason of this phenomenon is not because the normal Gmail service (@gmail.com) and Keio mail (@keio.jp) accounts are integrated.

(Q3) I have forwarded emails received by Keio mail to an email address of a cell phone, but recently I do not receive these emails on the cell phone.
(A3) Please set forwarding to the cell phone email address under Keio mail (Gmail). For the method, see "Automatically forwarding emails". And confirm whether or not the cell phone handles this as Spam. Please let email addressed as "keio-taro@a2.keio.jp" and with "@keio.jp" be delivered if, for example, the Keio mail address is keio-taro@a2.keio.jp.

(Q4) When I have logged in to Keio mail (Gmail), "Contains a redirect loop on this web site." was displayed.
(A4) Data stored in the browser's cache might cause this error messages to appear. See How To Clear the Browser's Cache and Other Records.

(Q5) I have received a notice from someone that e-mail was sent to a Keio e-mail address, but I has not arrived in my Keio mailbox.
(A5) Log in to Keio mail from the web and search for the sender from all e-mail. If you cannot find the e-mail by searching, it is possible that Gmail’s own filter decided it was junk mail, so check the junk mail folder.
