How to modify the SMTP port in Outlook, Thunderbird and Mail

Due to the migration of outgoing mail servers to the new data center, you may need to modify the outgoing server configuration in your email client. Therefore, in this tutorial, we explain how to modify this configuration in the main email clients: Mac Mail, Thunderbird and Outlook.  

Please note that there are three possible configurations and that you must apply one or another depending on your current configuration: 
  • 578 with TLS / Normal password
  • 587 with TLS / Normal password
  • 465 with SSL / Normal password

Important: The example images use the TLS/SSL configuration on port 465. If you need the other configuration, you must uncheck TLS/SSL and change the port to 25.

 

Mac Mail

Access Mac Mail, in the top menu click Mail --> Preferences..., in the preferences screen click the Accounts option and access Server Settings. There you must make the changes in the Outgoing Mail Server (SMTP) section. 




Thunderbird

Access Thunderbird and right-click on the account you want to modify. In the drop-down menu, click Settings. On the "Settings" screen, select the Outgoing Server (SMTP) section, select the account and click Edit, where you will be able to modify the outgoing configuration.




Outlook

Access your Outlook client and click the File option in the top menu. On the "Account Information" page, select the account to modify from the drop-down menu and click Account Settings. In the "Email" tab, select the account and click Change.... Access the More Settings... option and go to the Advanced tab, where you can modify the outgoing configuration.



After accepting the changes, your email account will be configured correctly and you will be able to send emails again.
