What is the difference between SSL and non-SSL Ports ?

  • When you use a standard POP or IMAP connection to download your email , your username and password is sent in clear text across the Internet.
  • Anyone in a position between your computer and mail server (Internet traffic) can potentially “intercept” your network traffic and clearly read your username and password.
  • SSL provides authentication and encryption during communication between your computer and email server. However, it does require additional set up time and is not suitable for every installation.


What is the difference between POP3 and IMAP ?

  • POP is a simple protocol, only allows downloading messages from your Inbox to your local computer. In POP3 the mail can only be accessed from a single device at a time.
  • IMAP allows you to view all the folders and messages from the mail server. Messages can be accessed across multiple devices.


  • For POP3 setup, it’s meant for download all the emails into email clients (local computer) and removed the email from server. The only backup of the email will be stored locally in your computer in this case
  • You can perform backup of the email, by export the email into .pst format.
  • If you want to keep messages on the server please make sure the setting Keep email on server is enabled or else all messages are automatically deleted from the server once downloaded to the email client


  • For IMAP setup, in general it always synchronize the same email content for your email client from the server.
  • If you delete messages from your email client, the email in the server will be deleted too. However, if you have a lot of transaction email with attachment, the email will appear “slowly” in your email client because the email constantly need to download from the server.
