For customers who can no longer send/receive emails with their mail software

We are sequentially disabling TLS1.0 / TLS1.1 support on all mail servers of our rental server services. We have notified you of this and requested changes to your mail server settings via an email with the following subject.

Delivery date and time:January 25, 2024

Subject:Notice regarding strengthening email server security (disabling TLS1.0/TLS1.1) for all rental servers 【Value Domain】

Due to the enhancement of mail server security (TLS1.0 / TLS1.1 support termination) on our rental servers,
you are required to update the settings of your mail software.

Please refer to the port change details described in the email body, or check the excerpt below and update your mail software settings accordingly.

(Excerpt from the email)

  • If you are using TLS1.0 / 1.1 with an old OS or mail software, you will not be able to connect from your mail software.
  • When connecting from mail software to the server, we recommend using the latest mail software and devices that support TLS1.2 or higher.
  • If switching to the latest mail software is difficult, it is possible to send/receive by changing the current mail software settings to disable encryption (do not use SSL/TLS).

    【 Configuration change details 】
    POPS: Port 995 → POP: Port 110
    SMTPS: Port 465 → SMTP Submission: Port 587
    IMAPS: Port 993 → IMAP: Port 143

For TLS1.2 support on your device or client software, please check the support status provided by each manufacturer.

We apologize for the inconvenience to our customers,
but we kindly ask for your understanding and cooperation to ensure stable operation of the service.
