Specific-use outgoing e-mail server

In the Tokyo Tech Mail System, only Tokyo Institute of Technology IC card holders can send e-mail. However, the System also provides a specific-use outgoing e-mail server as an alternative for e-mail transmission programs that users have installed on WWW servers, etc., for academic or research-related use.

1. How to use the server

Use the following server as the specific-use outgoing e-mail server.

filter-ex.nap.gsic.titech.ac.jp
(Please use "filter-ex" because "filter.nap.gsic.titech.ac.jp" is not supported by DKIM.)

Check the "From" address for outgoing e-mail.
  • Please designate existed Tokyo Tech Mail System addresses.
  • Please create an alias address as the follwing if you want to delete all e-mails which are received to "From" address.
    no-reply@xxxxx.titech.ac.jp -> null@nap.gsic.titech.ac.jp

If the (all) recipient address is titech domain address only

You do not need to submit an application.

If the recipient addresses include non-titech domain addresses

Fill out an application and submit it via campus mail.
* You do not need to submit an application to forward to an external address after sending to the Tokyo Tech Mail System alias address or to use the server via a CGI program installed on a WWW server proxy service.

Note

If you do worry about network failure or any other system failures, please consider getting the debug log or retry functions by e-mail transmission programs.
