Hi , I run EasyIoT server for years at windows PC. These days I bought raspberry pi and migrate server on it. All run like a charm except e-mail alert. I use gmail account and can't send mail from automation (at windows pc there was no problem two days ago). After few hours reading I found the solution: when run "sudo apt-get install mono-complete" at raspberry install mono 3.2.8 . Old version and can't work with gmail because of TLS 1.2. The minimum work version is 4.8. How to update:
1. Add the mono sourses. Execute the following commands:
mono -V
Mono JIT compiler version 5.12.0.226 (tarball Thu May 3 11:57:48 UTC 2018)

If you have successfully updated to a recent version of mono, you can restart Raspberry and Automation with gmail alert will work .
Thats all ...sorry for my English
