Hi guys!

I get this message when trying to send outgoing mail. I have just installed on a new laptop. Works fine off the old laptop. here's the message I am getting from my email server:


554 Nemesis ESMTP Service not available Transaction failed Reject due to policy restrictions.

Please note that, if your email header is not RFC 5321 and RFC 5322 compliant, your message will be rejected by our system.

This includes the following: 

   The following email headers included in your message must be syntactically correct: Date, From, Sender, To
   The following headers included in your email must be limited to just one each: BCC, CC, Date, From, Sender, Subject, To

Therefore, we would advise you to check that the above mentioned information provided by your system is correct. Should you need additional support, please contact your System Administrator.


meanwhile incoming mail is working fine so perhaps some configuration error on outgoing mail?

my address is [edited] @gmx.com

cheers

If you're experiencing issues with sending outgoing mail in Thunderbird, here are some troubleshooting steps you can try:

Check SMTP server settings: Verify that the SMTP server settings in Thunderbird are configured correctly. To do this, go to Thunderbird's main menu, select "Tools," and choose "Account Settings." In the Account Settings window, select the email account experiencing the issue and click on the "Server Settings" category. Ensure that the SMTP server hostname, port number, and connection security settings match the requirements of your email provider. If you're unsure about the correct settings, you can check with your email provider or consult their support documentation.

Check authentication settings: Confirm that the correct authentication method is selected for the SMTP server. In the same "Server Settings" section as mentioned above, check the "Authentication method" dropdown menu. Depending on your email provider, you may need to use options like "Password, Normal," "OAuth2," or "TLS Certificate" for authentication. Again, referring to your email provider's instructions can help determine the appropriate authentication method to use.
