A POP account is an email address
with a mailbox where your mail actually sits and
waits for you to get it. An alias is
an email address that routes the email to your
POP account.
What is the
difference between an alias and a POP email account?
Here's an analogy: A POP email account is like your postal mailbox at your
house or your PO Box at the Post Office. You use an email program to retrieve
the email for the account, just like you go to the end of the driveway or
to the Post office to your mailbox to retrieve your postal mail.
An alias, on the other hand, is like a mail forwarding address which forwards
to a mailbox somewhere that you specify. An alias forwards your email to
a POP account as a mail forwarding address forwards your mail from one postal
mail address to another (yes, you can have an alias to an alias as long as
it winds up somewhere retrievable.
Restated, a POP account is the final destination of email,
whereas an alias forwards or re-routes your email to that
final destination.
The reason
you would want to use an alias is for your convenience.
That could mean to have for professional look or
perhaps to note the source of an email inquiry
for marketing reasons. If you have on your web
site, info@mycoolproduct.com and you get an email
to that address you know its origin without setting
up an entirly new POP account on your computer.
An alias is the easiest to setup and integrate into your existing world.
If you already have an email account that you check somewhere (a POP account
no doubt), the alias can be configured to send your email to that existing
account. Nothing special need be done in your email software.
When creating a POP account, you must then configure your email program to
retrieve the messages, or check your mail at the server with a web mail program,
such as the one that comes with your hosting found at http://webmail.yourdomain.com. It
makes sense to have at least one (maybe a half dozen) POP accounts, whereas
you could have dozens of alias.
POP stands
for Post Office Protocol. It is a protocol that
mail programs use to download mail from a POP mail
server. The POP mail server receives your e-mail
when you are not connected to the Internet. Your
mail is stored on the server once you connect to
the server through your e-mail client. The e-mail
client then sends a request to the POP mail server,
and your e-mail is transferred from the server
to your computer.
