Mozilla Thunderbird Email Settings
Download Thunderbird here .
Open Thunderbird and click File > New > Existing Mail Account... (Note: If this is your first time using Thunderbird, the account wizard will begin automatically, in which case you should skip to Step Two below.)
Enter your Name as you would like others to see it when you send an email, then enter your full email address and password and click Continue.
Thunderbird will try to automatically identify and populate the fields. Once it completes, click on Manual config.
For both incoming and outgoing Server hostname enter mail.brownrice.com, then enter your FULL EMAIL ADDRESS in incoming and outgoing Username fields.
Then click Re-test, if this passes the test, click Done. If this fails the test, please double check your username/password/hostname settings and try again.
Ta-Da! You are now done and can start sending and receiving emails!
