How to Setup your Computerisms Hosted Email on Thunderbird

  • If this is your first time starting Thunderbird, it should automatically come up with a Set Up Your Existing Email Account page as shown in the image. If you already have accounts set up and are looking to add another, click on Local Folders in the lefthand menu bar and then Email under "Set Up Another Account"
  • Enter your Name, Email and Password and click on Continue
  • Verify that the server settings say the following (replacing domain.tld with your Computerisms hosted domain):
    • Incoming: IMAP mail.domain.tld SSL/TLS
    • Outgoing: SMTP mail.domain.tld SSL/TLS
    • Username: youremailaddress@domain.tld
  • If everything looks good, hit Done, and your setup should be done! If not, click on Configure manually
  • Make sure the Hostname for both Incoming and Outgoing Server is set to mail.domain.tld
    • If you are configuring IMAP, select IMAP under the protocol dropdown in the Incoming server section, select SSL/TLS for Connection Security, use port 993, and Normal Password authentication.
    • If you are configuring POP3, select POP3 under the protocol dropdown in the Incoming server section, select SSL/TLS for Connection Security, use port 995, and Normal Password authentication. (Note that we do not suggest POP3 setups except in special cases, ask us for more info if needed)
    • For SMTP, select SSL/TLS, use port 465 and Normal Password authentication.

  • Make sure that for the Username under both Incoming and Outgoing your full email address is filled in
  • Click on Re-test, and if you see a message like the one in the green box in the picture, hit Done
  • Your email is now setup! If you'd like, send a email to yourself to test functionality

    • This is the same password as you use to log into your email account
  • Select USe Password Manager to remember this password. to allow Thunderbird to save the password for later use (so it doesn't have to prompt you every time the calendar syncs)
  • Thunderbird should have detected your Calendar and be asking for Calendar Type; You want to select CalDAV for use with our calendar system
