Capture emails from multiple accounts at the same server. Here are the steps:
On your Cpanel, select Default Address.
Select Forward to email address, and fill up your desired email address and done. You can now send to any account with the same domain. Example, you want to have a separate account for facebook, so you create firstname.lastname@example.org, no need to create a separate account for it. All of your email will be captured to one account. These also works for those who have limited number of emails.
