[Bug] Cannot add self-signed imap email

[lgarlati]

Describe the bug A clear and concise description of what the bug is. When adding my self-signed SSL/TLS imap email, I get the following error:

Connection Failed An error occurred while establishing an SSL or TLS connection. The server's SSL certificate could not be verified for the following reasons:

• The server certificate has the following errors:
• A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

Expected behavior A clear and concise description of what you expected to happen. I should get a popup, like in thunderbird, asking if I want to trust this certificate.

Screenshots If applicable, add screenshots to help explain your problem.

Additional context Add any other context about the problem here. I'm 100% sure this email works, as it's perfectly fine with thunderbird on windows, and on my android phone.
