There are three types of mail available from Shetland Broadband:

1. POP3 (Post Office Protocol 3):
   The most recent version of a standard protocol for receiving e-mail. POP3 is a client/server protocol in which e-mail is received and held for you by your Internet server.
2. IMAP (Internet Message Access Protocol):
   A standard protocol for accessing e-mail from your local server. IMAP (the latest version is IMAP Version 4) is a client/server protocol in which e-mail is received and held for you by your Internet server.
3. Webmail:
   Software run by an ISP or online service that provides access to send, receive, and review e-mail using only your Web browser.

POP3 follows the basic idea that only one client requires access to mail on the server and it is best that mails stored locally. The advantages of POP3 e-mail are:

• Your mail is stored on your device and is therefore accessible whether you are online or offline.
• There is usually an option which allows you to leave your mail on the mail server also. If you do leave the mail on the server be aware that there may be limitations on the amount of server disk space available. If you exceed your space allocation you will loose older e-mails.
• You only need to connect to the internet to send and receive e-mails.
• POP3 is best if you:
  • Only access your e-mail from a single computer/device.
  • You want to read your e-mails or compose new e-mails without an internet connection, such as when traveling.

IMAP was designed to allow you access to emails stored on a remote mail server. This allows multiple clients or users to use the same mail account. You are therefore able to say, log in from your home or your office computer, and see the same emails and folder structure. All changes you make on your local computer are instantly synced to the mail server. The advantages of POP3 e-mail are:

• Mail is stored on remote server and accessible from many locations.
• Only headers are downloaded until content is explicitly requested allowing speedy loading.
• The mail on the server will be backed up periodically
• There is usually an option to store mail locally and this should be used for important (archived e-mails.
• You need to be online to manage your e-mails.
• IMAP is best if you:
  • If you wish to access your e-mail from multiple computers/devices.
  • You need instant notification of new e-mails.
  • You have good internet connectivity.

If you have multiple e-mail addresses then can all be configured separately as POP3 or IMAP.

Webmail is accessed online using a web browser making it available from any computer/device with a browser (Firefox, Chrome, Internet Explorer, Edge etc,) and an internet connection. Webmail is simple to access using the following procedure:

1. In the browser's address bar enter the URL “ http://webmail.calloo.co.uk/ ”. The address can be memorized in your bookmarks if required
2. When the page loads the login screen will be displayed.
3. For Username enter your e-mail address.
4. For Password enter your e-mail password as provided'
5. Click on the Login button and the mail interface will load.

It is important to remember that your e-mails are stored on the remote server and allowing a large accumulation of messages to build up will:

• Cause your e-mails to take longer and longer to load up, eventually maybe taking several minutes for a lot of stored mails.
• If the amount of storage used exceeds the allocated server allowance then older mails will be automatically deleted.

Therefore it is advisable to delete any mails no longer required at the earliest opportunity and if you have a lot of mail stored consider archiving the oldest to you own machine/device.

Webmail can be used to monitor POP3 and IMAP e-mail accounts if required but remember that some actions such as sending new e-mails may not synchronize with the master account.

When an account offers e-mail there is no fixed limit to the amount of e-mail addresses you may request. However if we consider the number of requests made to exceed a reasonable amount then we shall contact you to discuss the options available to you.
