What is an “email mailbox”, “POP mailbox” or “IMAP mailbox”?
An email mailbox is an email address that receives email messages and stores them on our servers. The messages wait on our servers until you read them using either our Webmail pages or a “POP” (aka “POP3”) or “IMAP” mail program such as Outlook or Apple Mail on your own computer.
E-mail mailboxes are the way most people read their email. The other way is a forwarding address, which sends the message to a different address you choose.
If you’re not sure whether you need a mailbox or a forwarding address, see Mailbox vs. Forwarding Address for help.
You'll probably want to create a mailbox for each person who reads email. For example, if three people named Rob, Mollie and Charlotte each need an email address, you might want to create mailboxes for firstname.lastname@example.org, email@example.com and firstname.lastname@example.org.
To learn how to create a mailbox, see the topic Creating Email Mailboxes.
Using role addresses with mailboxes and POP
Some people create mailboxes for generic “role” addresses, such as email@example.com and firstname.lastname@example.org. That works as long as you use Webmail or an IMAP program, or if only one person is reading the mailbox — but it can cause problems if two or more people are reading the same mailbox using POP mail programs on their own computer.
The reason is that as each person reads the incoming mail, their POP mail program will remove it from the server. That prevents the second person from seeing the messages the first person viewed.
To avoid this problem, you can use Webmail or IMAP, which don’t automatically remove messages when they’re viewed.
