mail in Thunderbird

The need to save space leads us to use all the necessary strategies to optimize it But the space is finite! “Also the Hosting” and emails are the most common cause of this consumption that leads us to use external email clients, other than Hosting, for example the mail in Thunderbird, in order to maintain the management of communications with customers by this means.

Thunderbird is a free, open source code email client available for the most common platforms such as GNU / Linux, Windows, OS X and mobile devices. Its use can mark a before and after in how you are going to manage the mail of your different domain accounts and sleep peacefully at night!

Do not be tormented by the lack of space, use your imagination but also use Thunderbird and learn to configure email accounts for your domains in this excellent desktop email client.

What data do you need to know?

The necessary data that you have to have on hand to set up an email account in Thunderbird are the following:

  • Username: [email protected]
  • Password: The one you entered when creating the email account.
  • Incoming mail server: (one)
  • Port: 995 (POP3) (SSL / TLS recommended).
  • Outgoing mail server: (one)
  • Port: 465 (SMTP) (SSL / TLS recommended).

(one) If you are a client of Websites Are Us you must replace XXX by the server you are staying on. If you access your cPanel, Mail, E-mail accounts, to the right of each email account you will find in the Actions column you will see the option Plus, when unfolding you will see Set up email client where you can get the manual configuration data of your email account (the one you are going to configure in Thunderbird).


  • IMAP email access coordinates between the server and your email application. The messages you have read, deleted or replied to will be displayed as such, both on the server and in the mail application.
  • POP3 is not coordinated with the server. Messages that the mail application marks as read, deleted, or replied to will not be displayed as such on the server. This means that future mail downloads with POP3 will show all messages as unread.

Much of the process of setting up an email account in Thunderbird is automatic (autoconfigurators from the most popular hosting providers). In the case of configurations that require manual intervention, pay close attention to the details regarding:

  • Name of the email account to configure.
  • Verify that the account password is not entered with spaces before or after.
  • Check the incoming and outgoing mail host.
  • Check the incoming and outgoing mail port.
  • Verify TLS / SSL security options (recommended).

In the following video I illustrate the process of setting up an email account, previously created in your Hosting Panel, so that you can manage it from Thunderbird.

Recommended checks

In case of problems or errors with sending or receiving emails from an account configured in Thunderbird, check the following points to verify that the cause is not due to any of the causes described:

If you are a Websites Are Us client and need help from the Support Department, you will need to provide screenshots that illustrate the process carried out, where you can see the ports configured for the incoming and outgoing servers and the security parameters (SSL).

Considerations with Antivirus and Thunderbird

Avast Antivirus uses an Email Shield with an advanced scanning method for incoming and outgoing emails on secure SSL / TLS connections It works transparently for most email clients, so there is usually no need for additional settings to work with your email provider.

Only users of email clients like Thunderbird that have their own certificate manager need additional configuration. Otherwise, you may receive warnings about invalid mail server certificates when you send and receive email messages.

Try disabling the Email Shield Avast to verify that this is the cause.
