Outbound Port 25 Blocking

  • Will users who have setup their own home mail servers be affected by Outbound Port 25 blocking?
    Not if they use an Asahi Net Fixed IP address.

    If using a dynamic IP address instead of a fixed IP address it will not be possible to send mail from a home mail server. Users may like to consider applying for and using an Asahi Net Fixed IP Address option.

    >> Fixed IP Address

    Alternatively, a change of settings to Asahi Net's Relay server will make it possible for users of a dynamic IP address to send their email from their home mail server.

    Relay server address : op25b.asahi-net.or.jp

    Please note that Asahi Net will not be able to offer support for your settings to use this relay server; your understanding is appreciated.
