Are you a small business owner using the Mozilla Thunderbird mail client?
For most people, the mozilla thunderbird has been the perfect solution to their mailing problems because of its dynamic features and the fact that it simplified the account set up process. Just recently I got emails, text messages and calls from many of my clients complaining about their not been able to send emails using their thunderbird mail client. While I was trying to figure out the problem I decided to upgrade to version 3.1 like most of you reading this mail. Then and there my problems began!
For over 24hours I could not send mails and like every normal person I got frustrated I decided reading up all the things and information I could lay my hands on, on the internet, yet none worked. I tried every solution proffered on the forums I visited but they just would not work. It took me donkey minutes to read almost all the materials on the Thunderbird knowledge base, I read and tried, restarted my system and Thunderbird numerous times but the “mail would not just send.” I spoke to some of our engineers about it, they tried all they could but nothing seemed to solve the problem.
I resulted to sending one of my clients an email via my company’s yahoo mail and it looked so unprofessional. My desperation to resolve the problem created in me the kind of determination that drove Cristiano Ronaldo to stardom. 😆
In the next few steps I would explain how to solve this problem(s). If you have this problem, prepare to smile, if you do not and you use Thunderbird, I would advise that you keep this GREAT resource somewhere safe.
How To fix the SMTP cannot send email problem
Some sample error messages:
*Sending of message failed.
An error occurred sending mail: Unable to authenticate to SMTP server smtp-server.wi.rr.com.
Sending of message failed.
*The message could not be sent because the connection to SMTP server mail.jetheights.com timed out. Try again or contact your network administrator.
According to Thunderbird,
An error occurred sending mail: Unable to authenticate to SMTP server ...
…when they send email.
This is caused by a bug in Thunderbird 2.0, where SMTP configuration settings that were previously ignored are now being used. Specifically, in Thunderbird 2, if an SMTP server did not require authentication, data in the user name / password fields was ignored. In Thunderbird 3, however, data in the user name and password fields is sent whether or not the server requires the data, causing some servers to reject the connection.
1. Try sending another mail to be sure you still have the problem. If you do not, that is another miracle I just performed. 😆 but if you still do, just to step 2 and let’s ride.
2. There are two sides to it and you just have to choose at this juncture where you belong.
a: You are willing to delete or let go of any message in your inbox for at least one of your least used emails. (for those who do not have sensitive information in their inbox. (Shorter steps)
b: You have sensitive information and cannot risk deleting them. (A bit longer)
3. If you chose “a” above simply click Tools~Account Settings~Account actions~Delete the mail account.
Then jump to step……………………9
If you chose “b” above follow this next steps.
4. Log in into your hosting control Panel (CP), if you do not have access to your control panel you can ask you web hostsupport team to simply help you create a new email and send you the configuration details once you get that jump to step…………………………9
If your hosting account cannot have more than one email jump to step ………12 and try the troubleshooting.
5.In your CP click on Email accounts. This is where you normally create new email accounts for your domain.
6.Create a new account and don’t forget your password as you would need it later. You can use the same password as the other mail(s) not sending out emails.
7. Access your email configuration detail (manual settings)
8. Launch your Mozilla Thunderbird mail client.
9.Go to tools at the top bar (click) ~Account settings~ Scroll down and click Account Actions~ Add mail account~
Put in you name, email address just created(or deleted in step 3 above) and password~ create.
10. Here is the tricky part, Thunderbird tries to configure your mail account for you so it looks for the best incoming and outgoing server route possible.
Watch closely to make sure that both incoming and outgoing settings show a green ball to the left side, if not cancel and restart….Go back to step 9. This is because Thunderbird will choose best settings for you.
11. Once this is done, try sending an email with the new email address and bang ! If you have any problems at this stage repeat the steps above.
12. To configure the other emails not working. Click Tools~Account settings~On the left hand side, scroll down till you see Outgoing Server (SMTP) then click~ Set the newly created account as default (Set Default)
Click to Edit the SMTP details of the new email
Note the configuration for the new email is different from the existing ones
There are two most important things here.
a: Default Port : changes from 25 to 465 or vice versa.
b: Connection security sometimes changes from STARTTLS to SSL/TLS
13. Note the two main details without forgetting your username. Click on any email not working~Edit and make sure you change both the port number to 465 and the connection security to the appropriate one.
14. Test to check that your email now works fine! Bingo!!
