In order to send and receive mail you will need to setup up E-mail client software on your computer. Some examples of common E-mail client programs include Outlook / Outlook Express, Eudora, Thunderbird (see below), and many others.
Setting Up POP3/IMAP Accounts:
(In the following examples, we use "example-site.com" in place of domain name attached to your mail account)
Under Outgoing Mail Server, ensure that the option "My Server requires authentication" is checked. Under Settings, ensure that "Use same settings as my incoming mail server" is checked.
For Thunderbird (7.0) Users:
Thats it! Your E-mail client software should now be configured properly to send and receive e-mail. Be sure to consider carefully the option of whether to "Leave mail on the server", as this will allow you to check all your mail from more than one computer without fearing of it being lost if a computer crashes or is inaccessible, but this also can cause your mail to pile up, and if you receive a large amount of mail or have many sub-accounts that are using this option, you could find yourself nearing your quota much sooner than you would if all mail is downloaded locally and then deleted from the server.
