Enable SMTP Authentication for Mozilla Thunderbird 3.x

Enable SMTP Authentication

  1. Open Thunderbird Mail. From the Tools menu select Account Settings. The Account Settings box appears.
  2. In the white area on the left, select the entry Outgoing Server (SMTP). The Outgoing Server (SMTP) Settings appear on the right.
  3. In the Server Name box check that the entry is set to mail.his.com
  4. Change the Port from 25 to 587 *
  5. Verify that the Use name and password box is checked. Click on the box to check it, if it is not checked.
  6. In the User Name box enter your email address.
  7. Click the OK button on the bottom. Authentication has now been enabled.
    Please note: You will be prompted for your password the first time that you send email. Be sure to check the box Use Password Manager to remember the password, to avoid having to enter it every time that you send email.


* Note:
An increasing number of cable and DSL providers (Comcast, Cox, Roadrunner, Verizon, etc...) are blocking the default SMTP port 25 except for their own mail servers. This is being done to help reduce the amount of spam sent from infected customer PCs.
Symptoms: you get an error sending mail, saying "could not connect to mail.his.com".
Solution:In order to send email through your HIS mail server from your cable/DSL account you will need to use SMTP port 587 for mail.his.com.
