Can I send email through PlusNet using my current old email address? My old free ISP doesn't like sending email through its smtp server on ADSL anymore. It only accepts the old dial up but I want to keep using my old email address for sending email using ADSL. I can receive it fine. Can having a static IP address help?

If you are connected to PlusNet, then you can send all your email through the PlusNet smarthost: relay.plus.net - you can use whatever email address you like.

Doesn't make any difference.
