Email Hosting typically includes:

• Hosting for your email addresses;
• Providing administration capabilities to:
  • Add/change/delete email addresses;
  • Change passwords;
  • Adjust the SPAM filtering;
• Providing access for Email Client programs (usually POP3 and/or IMAP4);
• Usually providing a form of WebMail access (using your standard web browser).

This is a basic service that can be provided without having a web site or if the website is hosted elsewhere, but allowing you to send and receive emails under your domain name.
