On March 18 (Wed), 2015 at 9:00 am, ACCC will limit the possible destinations of relay mails via the receiving gateway, i.e. “smtpgwin.cc.tsukuba.ac.jp” (hereinafter referred to as “smtpgwin”) to university addresses (such as those with “tsukuba.ac.jp” or those approved by the subnetwork committee). From then on, it will be impossible to send outgoing mails (or relay mails) via smtpgwin. Originally, smtpgwin was installed to send inbound mails to university e-mail addresses. Some users, however, send outgoing mails (or relay mails) via smtpgwin. This is against ACCC’s guidelines for mail gateway operation, so ACCC has decided to take measures to stop it.
If you are using smtpgwin to relay your mails, please configure your computer not to do so by the date above.
