Mozilla Thunderbird is a free Email client from the people that brought you Firefox. It’s fast, secure, and supports extensive plug-ins that add additional functionality. Thunderbird works under Windows, Mac OS X, and Linux. These instructions are for version 9.0
If you are opening Thunderbird for the first time, the new account setup screen will come up automatically. Otherwise, select Account Settings.. from the Tools menu. Select “Add Mail Account…” from the Account Actions pulldown menu in the lower left on the window.
Enter the name and email address you want to appear on your outgoing email. Type in your password and check “Remember password” if you want your password to be stored in Thunderbird. Click Continue.
Thunderbird will scan common host names under the domain. If you are using an lmi.net email address, it will find the correct Incoming server, but not the correct Outgoing. You need to click the Manual Config button. (If you are not using an lmi.net email address, it will bring up the manual config screen right away.
Here you need to choose if you are going to use POP or IMAP to check your mail (see this tech note if you are unsure what to choose.)
Type in mail.lmi.net for both incoming and outgoing mail server (regardless if you are using POP or IMAP).
If you are using an lmi.net address, the username will be just the first part (before the ‘@lmi.net’). If you are using another domain name, enter your entire email address in the Username field.
Then click the Re-test button. The port numbers should then get filled in, after which you can clock the “Create Account” button to finish.
