SMTP Server Settings
Sending Emails with various servers can be a challenge. In this blog article we like to collect the settings needed for using our SendMail functions in FileMaker or CURLEmailMBS class in Xojo to send emails. As you see we always prefer to use encryption.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.
