Additional Key Points to Remember
Aside from the email settings mentioned above, it is also important to take note of the following points:
- If the automatic setup fails, you can manually enter your settings by selecting Manual setup or other server types.
- Please select More Settings → Outgoing Server and check the box for "My outgoing server (SMTP) requires authentication" when creating your account.
💡 Note: If you're having trouble connecting or getting a certificate warning, turn off SSL/TLS encryption and adjust the incoming server port to 143.
Keeping this in mind should allow you to work with StackMail more efficiently.

POP3 vs. IMAP: What's The Difference
Even though both protocols are Message Accessing Agents, POP and IMAP operate differently in email access, making one more advantageous than the other in specific situations.
Originally known as the Post Office Protocol, POP was the first widely used email protocol on the internet in its beginnings.
When you use the POP3 protocol to access your emails, a copy of the emails gets created and saved locally on your computer. The originals normally get removed from the mail server; however, this is not always the case.
Many times, emails are associated with a single device. Another email client or device can no longer view the email once downloaded onto one device and withdrawn from the mail server.
IMAP stands for Internet Message Access Protocol. Unlike POP, IMAP allows you to access the same mailbox from numerous devices because your messages remain on the server.
The IMAP protocol connects your client application to your mail server, allowing you to control your emails on the mail server itself directly. In this configuration, your mail server, rather than your local computer, serves as the primary storage location for your emails.
