There are two kinds of email address's you can use. Lets start with the "catch all" method:
With the catch all method, you don't have to worry about setting up individual pop mail accounts. Simply set your email client to your "default" email address (displayed in your control panel), and "all" email sent to email@example.com will land in this box, or whatever you've set your default address to. This is an easy way to catch all email sent to your domain.
In your Email client, feel free to configure multiple outgoing accounts at firstname.lastname@example.org. It really doesn't matter, as email@example.com will land in the default account. Therefore, you would configure all of your email accounts with the "same" Username and Password as your "Default domain Email Account."
EXAMPLE: Let's say you want to receive mail from firstname.lastname@example.org and email@example.com. If both of these addresses are the ones you'll be using, then the only thing that changes is the address - the Username and Password is "always" the same.
In this case, you configure a "private" pop email account for one or many users who will be receiving and sending email from your domain. Once an email address is configured as a pop mail account, it operates privately and independently from your main standard/default mail system. Any mail sent to a private pop mail account "can only be received" by logging into that account with the separate username and password you have assigned it.
Your default "catch all" account will not intercept any mail being sent to a
pop mail account, which is what makes it 'private'. Pop 3 accounts are useful if
there are a number of people (for example employees) who would each need a
private email account.
1. Login to your control panel (http://www.your-domain.com:2082)
That's it, done! Your private POP 3 Email Account is now ready for use. If
you're a little lost on how to manually configure an email account into your
mail reader, please see the detailed tutorials on how to configure Outlook and
Netscape mail readers.
