Look under the tools menu (alt+T) at account settings and click on the account name. Note the outgoing server (SMTP) listed towards the bottom of the panel. Make sure it is for the account you think it is. Change it if it is wrong.

Now go to the bottom of the accounts list and locate the outgoing server (SMTP) entry there. When you click on it you will be presented with a list of SMTP server that Thunderbird knows about (the same list that appears in the account settings under account name) select the appropriate SMTP server entry and click edit.

ensure the settings are

Server Name: smtphm.sympatico.ca Port: 587 (or 25 if port 587 does not work) Connection Security: SSL/TLS (If that does not work STARTTLS) Authentication Method: Normal Password

  • Do you use Thunderbird add-ons?
  • Who is the email provider?
