Unable to send email to server with Self-signed certificate

[akaSorin]

Description

Similar to this issue https://github.com/Fallenbagel/jellyseerr/issues/187, I'm unable to send emails with the "Allow self-signed certificate" option enabled, but the server has been conrrectly used by other applications on my network like nextcloud and voultwarden.

To make things worse, the debug logs are not very verbose, which makes it a bit difficult to get to the level of detail we need.

EDIT: Good news, the issue seems to affect only the test functionality, not the actual notifications

Version

2.3.0

Steps to Reproduce

1. Go to Settings > Notifications > Email
2. Type the SMTP Server data, port 587, STARTTLS if available
3. Mark Allow Self-Signed Certificates
4. Save and send Test Email
