SMTP Server Settings

Bei checking certificates, we can detect and avoid giving our password to a transparent proxy. And we enable TLSv1.2 for all here and require encrypted connection. It's important to test and verify this, as I once run into a hotel reading my emails to count them and prevent spamming.
