What is SMTP?

SMTP (Simple Mail Transfer Protocol) is a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP3 or IMAP.

If you wish to use Register365 for your outgoing mail service, for example, if you move around a lot and prefer not to have to change the outgoing mail server depending on which ISP you are connecting through, then you can purchase the Authenticated SMTP service

What is Authenticated SMTP?

Authenticated SMTP allows you to send emails through Register365 mail servers, using a username and password supplied by us. This can be used when your ISP (Internet Service Provider) does not provide an outgoing mail server, or if you use a machine which logs in from various locations, such as a laptop.

Register365 Authenticated SMTP may not be available with your ISP. You should check with your ISP whether they block default port 25 (SMTP) access through their network before purchasing Authenticated SMTP, or allow access to external SMTP servers through their network. If they block port 25, or prevent external access, this service will not be available to you.

Only 1 Authenticated SMTP package is required per domain name as it covers all mailboxes.
