I am trying to implement an SMTP email send in react native. I tried the same steps explained in the link https://github.com/angelos3lex/react-native-smtp-mailer/. But all the time when I try to send the mail, an alert with an error message "Error: could not connect to SMTP" is showing.Initially, I created a new project and replaced the App.js with https://github.com/angelos3lex/react-native-smtp-mailer/blob/master/example/App.js. The relevant fields like port, server, to and from email address are modified with my details.
Since I am new to react native, I don't know where I went wrong. Can you please help me?
