i saved the mail.properties file in the server neighborhood
and run:java -jar Arduino/blynk-server/server-0.27.0.jar -dataFolder Arduino/blynk-server/blynk-data
I faced the same problem. In my case the solution was to put my mail credentials inside the mail.properties file, but still inside the server jar. I used winrar to do this, like this:
1 I rename the jar to rar
2 I opened the jar as winrar
3 I edited the mail.properties file and saved it
4 winrar asked me if I wanted to update the mail.properties file
5 I said yes and I succeeded
