Email Protocols Explanation

POP (Post office protocol) is a one-way download of your messages that allows you to access your mail with a mail program like Outlook Express, Thunderbird or Apple Mail. POP only offers one-way communication, which means the actions you take in the mail program (like marking a message as read) won’t be synced to Webmail.

A domain is a name for an IP address and is more commonly recognized as a website or web address. For example, Google.com is a domain.

TLS (Transport Layer Security) is a way of changing data such as your username and password into code as it travels across the Internet so that the data will be secured and private. With mail delivery, TLS begins with an unsecured connection to the mail servers and then upgrades to a secured connection once information is sent.

SMTP (Simple Mail Transfer Protocol) is a set of standard Internet procedures by which two email providers (ex. Gmail, Yahoo Mail), transfer email messages to one another’s mail servers.

IMAP offers two-way communication between your Webmail and your email client. This means when you log in to Webmail using a web browser, actions you perform on email clients and mobile devices (ex: putting mail in a ‘work’ folder) will instantly and automatically appear in Webmail (ex: it will already have a ‘work’ label on that email the next time you sign in).

IMAP also provides a better method to access your mail from multiple devices. If you check your email at work, on your mobile phone, and again at home, IMAP ensures that new mail is accessible from any device at any given time.

Finally, IMAP offers a more stable experience overall. Whereas POP is prone to lose messages or downloading the same messages multiple times, IMAP avoids this through two-way syncing capabilities between your mail clients and your Webmail.
