Email control panels allow instant creation of email POP3, forwards, and aliases.
A POP3 account is a stand-alone incoming email account. So, if you create u: john p: doe it all mail sent to email@example.com, it will be routed to the joe email account. The user joe can then check this mail by logging into mail.domain.com using his username and password. Note: all usernames automatically have a determined amount of letters of the domain name appended to the beginning of the username. So if john was a another domain user, the user would use mail.somedomain.net as his incoming email server and use powerjohn as his login name to retrieve mail sent to firstname.lastname@example.org
An alias forwards mail sent to one address to another POP3 account within your domain. For example if our recently created john account was going to
receive all mail sent to email@example.com, we would setup sales as an alias to john. Note: by default, all names are not configured to the root account. So if you sent a message to firstname.lastname@example.org it would be sent to your main root account, unless you had set it up as an alias, forward or POP3.
A forward account forwards mail sent to email@example.com to an address completely out of your domain. For example if john had an AOL account and wanted to check all his mail there, you could setup john to forward to firstname.lastname@example.org.
