Note
Note 1: It is only available from the campus network.
Points to note when using mail server services¶
Once you have completed user account registration, the mail server administrator will provide you with a user account and initial password. Please note the following points when using it.
Caution
Be sure to change your initial password.
Reception of email with the virtual domain server is restricted to only from the campus network.
Please set the settings so that emails are not left on the server.
Contact information for mail server services¶
The mail server for each domain is managed by the mail server administrator for each domain.
Caution
For requests such as issuing a user account or registering or deleting a mailing list, please contact the mail server administrator for the relevant domain.
Also, if you have forgotten your password or are experiencing problems, please first contact the mail server administrator for the domain you are using.
About settings for receiving email clients¶
The virtual domain server is a shared server. Please set the settings so that no e-mails are left on the server, and frequently retrieve received e-mails. There is a limit to the storage capacity (2GB). This is because if each user leaves their mail on the virtual domain server, it will consume a large amount of disk space, and in the worst case, the service will stop.
Caution
If you have a UEC Account , please help us by forwarding the email to @UEC email, etc.

About SMTP connection timeout¶
Depending on the status of the email sending server, in rare cases a timeout may occur when sending an email, resulting in failure to send the email. Please set the SMTP connection timeout to approximately 300 seconds in advance.
This is a so-called DoS attack in which a large amount of spam email is sent to the university’s email sending server (/srv/all/uecmail/) in a short period of time, and as a result, even if an SMTP connection is established, emails cannot be sent. This is because a temporary problem will occur.
To use from an off-campus network¶
The virtual domain server’s mail server service does not have a way to directly receive mail from outside the university. (Note 4)
As an alternative, if you have a UEC account, you can use forwarding to an off-campus network and an email service that can send and receive emails, or you can use remote access to send and receive emails.
Using forwarding
@UEC Mail allows you to send and receive emails from off-campus. Please consider forwarding it here. For more information, please refer to On-campus Email .
Using remote access
The Information Technology Center provides Access VPN as a remote access service. Please use the port forwarding function of the Access VPN service. For more information, please refer to VPN.
If you do not have a UEC account, we apologize, but there is no way to use the services provided by the Information Technology Center from an off-campus network. Please consider forwarding to an off-campus free email service.
Regarding the free email services you actually use, please follow the policies of each domain.
Note
Note 4: Emails can be sent from an off-campus network.
