E-mail aliases allow you to setup as many e-mail addresses as you would like for any domain. E-mail aliases are just "aliases" of a POP3 account within your domain. Aliases can only be setup to direct something@yourdomain.com (Alias) to somethingelse@yourdomain.com (POP3 account). This means that they will not be able to point to another domain. You can have multiple aliases pointing to the same POP3 account.

An Example: say John is the president of your business. He needs all e-mail directed to president@yourdomain.com, pres@yourdomain.com, and john@yourdomain.com to be directed to the POP3 account of his, which is going to be the john@yourdomain.com e-mail address. President@yourdomain.com and pres@yourdomain.com would both be e-mail aliases of john@yourdomain.com and all mail sent to any of these three e-mail addresses would be directed to the john@yourdomain.com POP3 account.

TeamMediaOnline does not restrict the amount of aliases that you setup.
