Frequently Asked Questions

How does email work?

When you send an email, your computer talks to the mail server at your email provider using SMTP. When the mail server receives your email, it contacts a DNS server to look up the IP address of the domain of the email to find out where the email is meant to be sent. Then it asks if the domain has any MX or mail exchange servers on it. With this info, the message is sent from your mail server to the recipients MX server. This server decides where to put your email, so the recipient can download the email usually using POP3, IMAP or just having it displayed in webmail.

What is spam?

Spam is the unsolicited sending of email to users who don't want to receive it.
