Question [SSL/TLS] Error connecting to secure SMTP server


Hello

I know this is a Linux forum, but I don't really know where else to ask for security-related issues.

I'm trying to send e-mails from an old Windows application and connect to a secure SMTP.

When connecting, the client fails with the following error message:
Quote:
SSL Negotiation Failed: Unknown Error The connection with the server has been lost. Cause: (200)".
I attached a screenshot.

Could it be that the e-mail client simply needs updated/new SSL certificates from the SMTP server?

Thank you.

Yes, I believe that is the problem.
Here's a post from earlier this year with the same problem: http://compgroups.net/comp.mail.eudo...rver-s/2974797

Thanks much, but even after importing the certificate sent by Vivaldi, the error message still pops up when trying to send an e-mail through their secured SMTP server:
