1. Tokyo Tech Mail accounts

Tokyo Institute of Technology IC card holders who have registered their name readings receive an e-mail address on the "m.titech.ac.jp" domain. This is your Tokyo Tech Mail account. The Tokyo Tech Mail System is what allows users to send and receive messages with their accounts. In the Tokyo Tech Mail System, account holders get unconditional access to e-mail storage areas (called "spools").

Tokyo Tech Mail specifications

  • Spool size: 20 GB for faculty members; 8 GB for students
  • Outgoing/incoming e-mail size: Up to 50 MB
  • Webmail functionality
  • Support for SMTPS, POP3S, and IMAPS
  • Spam filters
  • E-mail forwarding
  • Messages in the Webmail "Trash" and "Spam" folders are automatically deleted after 30 days

Tokyo Tech Mail expiration date

Although Webmail is technically only accessible to you while you are enrolled at the Tokyo Institute of Technology, you can continue to use your address for 90 days after your IC card expires. During this extension period, you can use your Tokyo Institute of Technology Portal matrix code to access Webmail.

Once you have successfully registered your Tokyo Tech Mail address, you can keep it active if you continue on to further schooling at the Tokyo Institute of Technology and reactivate it if you choose to reenroll at the Tokyo Institute of Technology. Transferring your ID (your staff number or student number) from a previous IC card when you apply for a new IC card allows you to keep using the Tokyo Tech Mail address linked to your old card.

After a Tokyo Tech Mail address has reached the end of its extension period (90 days after the corresponding IC card expires), the system permanently deletes all the data associated with the account. We recommend making backups of your e-mail to be safe.

2. Webmail

Webmail is the browser-based e-mail system that users can access via the Portal. Users do not have to configure any special settings on their computers to use Webmail—as long as you have an Internet connection, you can access Webmail from a computer or other terminal anywhere, anytime.

See Online guides: Webmail for more information on using Webmail.

3. Using an e-mail application to send and receive e-mail

You can use Outlook, Thunderbird, and other e-mail applications to send and receive e-mail with your Tokyo Tech Mail account. Tokyo Tech Mail uses SSL encryption in order to ensure secure communication routes. This means that your e-mail application needs to be compatible with SSL encryption.

When using an e-mail application to access Tokyo Tech Mail, you can choose to receive messages via POP3 or IMAP. If you use POP3, your application will download all your messages from the server to your hard disk. If you use IMAP, on the other hand, you can manage your e-mails on the server (and, if you want to, you can also configure your application to save messages to your computer).

See Online guides: Setting up e-mail applications for more information on how to configure e-mail applications.

4. Spam filters

Tokyo Tech Mail currently employs filtering techniques to identify spam automatically. Under this setup, the system adds "X-titech-spam" to the header (information at the top of every e-mail, such as the "From" or "Reply-to" fields) of each message marked as spam.
If you use Webmail or your e-mail application's sorting feature, you can sort e-mails to various folders based on the corresponding header information.

See Online guides: Spam filters for more information on using spam filters.

Notes

  • Spam filters are not completely failsafe; they do not always detect and filter spam correctly. The results of test operations show that the filters generally have an accuracy rate of around 90%.
  • In extremely rare cases, spam filters may mistake a regular e-mail for spam.
