[Important] Implementation of "Outbound Port 25 Blocking"

Thank you for using SpinNet.

We will start to implement "Outbound Port 25 Blocking" called "OP25B" for short, to reduce SPAM mails from this month.

Due to the implementation of OP25B, customers using SpinNet’s E-mail service with another ISP’s Internet connection will be required to set up their E-mail software with "Submission Port 587 and POP before SMTP" settings.
Please be aware that these customers will not be able to send E-mailsthrough SpinNet mail servers without changing their settings.

In order to implement OP25B, maintenance work will be done sequentially in each area. Some customers will not be able to use SpinNet connection for a short while during this maintenance.
Please refer to our homepage for the updated maintenance information.
