In Your Control Panel

The first thing to do is to set up a new mailbox. In the main nav bar, click Mailboxes/Users. > Click "Add User" > In the Username field, type the part of the email address that will show up before the @ symbol. > In the Fullname field, type the user's true name. > In the password field, type a password. > Leave disk Quota alone. > Do not check FTP. > Click Add.

It's possible that your account was set up with the same userID (also called login) that you want for your email address.  If this is the case then your mailbox is ready to go using the same password as you use for your hosting account.  You only have to set up your email account in Outlook Express in this case.

Email Interfaces

Once your account is set up, you have 2 alternative interfaces that you can use to work with email -- web-based, or local client such as Outlook Express.  To access the web-based interface go to domain.com/squirrelmail where domain.com is your domain.  This interface works just like Yahoo! Mail or Hotmail.  The squirrelmail interface is fully operational as soon as your account is set up in the control Panel.  A local client still requires a bit of configuration on your end.

Click on Mailboxes/Users in the left column main nav bar.

Click on Add User.

The Username is the part of the email address that is before the @ symbol.  Also, type your full name or the full name of the person who will be using this email account.  Type a password (all lower case -- no spaces.)  Click Add.

Outlook Express Configuration

Do Tools > Accounts > Add > Mail >

Type in the email address you want to use.

Incoming and outgoing mail servers are both mail.yourdomain.com where yourdomain.com is the domain you're using for your site.

Account name is your email address.

Almost done.  :)

Make sure all the setting are correct by doing Tools > Accounts > Click on the new account to highlight > Properties.

Click on the Servers tab, and make sure your dialog looks like this -- with "log on using secure password authentication" NOT checked -- and with "my server requires authentication" CHECKED.

Click the Settings button next to "my server requires authentication," and make sure "use same settings as my incoming mail server" is selected.
