1. What is SMTP delivery and who is it suitable for?

SMTP stands for Simple Mail Transfer Protocol and is a means by which mail is transferred from one mail server to another. Usually SMTP is used in combination with other mail protocols such as POP3 or IMAP; these other protocols running on the local server from which you collect your mail.

With SMTP delivery all mail to your Plusnet email address is routed directly to a mail server of your choosing.

It's most commonly used by business customers that want to handle all of their email directly.

2. Static IP addresses

To use SMTP delivery on your account, you'll need a static IP address.

  • Business accounts use static IP addresses
  • Residential accounts offer dynamic IP addresses (with some exceptions, see our IP Addresses guide)

If you're using a residential account and need to switch to a static IP, go to Control Your Broadband and follow the on-screen instructions. You'll find it within Connection Settings in the Member Centre.
