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.

For Gmail you need to allow less secure apps on website in your account settings or with 2FA create an app specific password. I would recommend a separate gmail account for sending emails. | ||
