Compatibility with Exim

I installed this plugin and use it with my Exim email server. I can send test emails only if i set Encryption to None. If I set Encryption to SSL or TSL, test mails can’t be sent. Are there any compatibility issues with Exim? What email servers should be used as i want to use encryption?
