Title: Compatibility with Exim Last modified: August 19, 2018 --- # Compatibility with Exim * [wuboris](https://wordpress.org/support/users/wuboris/) * (@wuboris) * [7 years, 10 months ago](https://wordpress.org/support/topic/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? ——————————————————- Versions: WordPress: 4.7.3 WordPress MS: No PHP: 7.0.7 WP Mail SMTP: 1.3.3 * Params: Mailer: smtp Constants: No ErrorInfo: SMTP connect() failed.
