Thunderbird identifies the first SMTP account that you set up as being the default account. Most SMTP mail servers are set up to allow e-mail accounts from other ISPs to be run through them. Unlike setting up an e-mail retrieval for inbound e-mail, with SMTP, a single SMTP setup can be used to cover all of your e-mail addresses, regardless of how many different ISPs are involved.

However, there are fewer factors involved when setting up the SMTP section in Thunderbird, so isolating the problem can be much simpler. Outbound e-mail problems can be frustrating to deal with because you rarely see an indicator as to what might be causing the problem. The e-mail is stored on the server until retrieved by another e-mail client using a POP3 or IMAP retrieval protocol. SMTP is generally used to send messages from a mail client (Thunderbird) to a mail server. SMTP is the standard for e-mail transmissions across the Internet. Outbound e-mail uses a process called SMTP (simple mail transport protocol). Troubleshooting these types of problems in Mozilla’s Thunderbird is fairly easy if you understand how outbound e-mail works. Such a filter could block or even delete the emails addressed to you preventing them from landing in your inbox.Outgoing e-mail problems can sometimes be more difficult to troubleshoot than incoming e-mail problems. Contact your ISP and check if they set up a spam filter. If you have problems receiving emails, check if everything is up and running on your ISP’s end. Switch to another port or contact your ISP for further help if you still can’t send emails. Some Internet Service Providers tend to block outgoing emails on certain ports (port 25). You can find the list of previous Thunderbird versions on Mozilla’s support page. The problem is that you won’t be able to send or receive emails if your provider does not support the latest TLS network encryption protocols.Īs a workaround, you can rollback Thunderbird. Thunderbird 78 and higher require enhanced TLS security standards. Save the changes and restart your computer.Use the slider to disable SSL/TLS protocol filtering.Click on Web and email (or type ‘ tls‘ in the search bar).Use this method if you can’t receive emails on Thunderbird. If you’re using a security tool from ESET, try turning off SSL filtering. That’s why you need to get your security programs to recognize and trust the updated Thunderbird version. Your antivirus/firewall may not trust the new Thunderbird version. If this problem occurred shortly after you updated Thunderbird, whitelisting the email tool should fix it. For detailed instructions, go to your antivirus/firewall official support page. The steps to follow are different depending on the antivirus/firewall you’re using. Hit the Allow another app button and add Thunderbird to the list.Then click on Allow an app through firewall.

If you can send and receive emails with the antivirus and firewall off, whitelist Thunderbird. To test if your antivirus or firewall is blocking outgoing emails, simply disable the tools. Or they could be blocking the emails coming to your inbox. Your antivirus or firewall might be preventing Thunderbird from delivering your messages. Whitelist Thunderbird or Disable Your Antivirus/Firewall Select Server settings and make sure you’re using the correct IMAP Server settings.įor more information on the IMAP settings to use, go to the official webpage of your email account provider.

That’s why you need to make sure you’re using the correct SMTP server settings.Įnsure you’re not trying to send emails from Thunderbird using the SMTP server of another email service. Not using the correct SMTP settings may prevent you from sending emails using Thunderbird. The server then distributes them to the recipients. In other words, the emails you send are first collected by the SMTP server. The SMTP server (Simple Mail Transfer Protocol) plays the role of the mailman in the email world. Use this method if you can’t send emails. Cannot Send or Receive Emails on Thunderbird Check Your SMTP Server Settings
