Additional Key Points to Remember

Beyond email settings, there are more points and suggestions to consider for utilizing EarthLink smoothly.

💡 Note: If you want to use TLS security on your incoming connections, under Incoming, change the "Use the following type of encrypted connection" option to TLS. Then, select None for the Outgoing option.

Second, if you use EarthLink's spamBlocker, you can see your Suspect and Known Spam folders in your mail application or on your mobile device when you use IMAP. In other words, you will not have to visit WebMail to check for spam-tagged emails anymore. You can move them directly from your Spam folder to your Inbox if you want.

Finally, if you are already using POP, most programs will urge you to switch to IMAP and treat it as a new mail account. IMAP should get added to your mail program as a new setup rather than editing an existing POP setup.

💡 Note: Since POP and IMAP work differently, changes to POP or IMAP configurations may result in lost or missing messages.

Furthermore, IMAP allows you to employ STARTTLS as a security option when downloading your emails. STARTTLS is a type of SSL encryption across your computer and the EarthLink email server that helps protect your email content from being intercepted and read when you download it from the EarthLink server.

When using IMAP, you can enable STARTTLS by heading to your mail client's advanced email settings and choosing it as the method of security for the Incoming server.

POP3 vs. IMAP: What's The Difference

Incoming messages get handled via the POP3 and IMAP protocols. However, the differences between them make one more useful in some situations than the other.

POP3, or Post Office Protocol, enables you to use your inbox like a post office, downloading emails to your computer and deleting them from the mail server.

On the other hand, IMAP, or Internet message access protocol, allows you to read the same messages across many mail applications or webmail interfaces. Because IMAP stores emails on the mail server rather than on your PC, this feature is accessible.

In the end, your choice of protocol is determined by how you wish to access your messages. POP3 should be utilized if you only use one client application on a single dedicated device, such as your work computer at the office, and you have a large mail history and limited storage capacity.

On the other hand, you should use IMAP if you check your mailing on several devices, such as a phone, a computer, a tablet, etc. You want your devices to sync, including emails and any organizational structure you have built.

Because of its flexibility, many people adopt IMAP rather than POP3.
