Java Email
This java tutorial is to send email in java using Gmail. Example java email program will use Gmail SMTP server to send mail.
There is not much involved to discuss as javamail api takes care of everything. It is all about just using the JavaMail api. By every release, javamail api is getting sophisticated and so it is an easy job.
I have used JavaMail API version 1.4.5 and should add two jars as dependency for sending email mailapi.jar and smtp.jar

- My example program uses Gmail SMTP server.
- Mail authentication is set to true and need to give sender’s email and password. That is, we cannot send email anonymously.
- In the program you can modify it to send to multiple To emails.
- Sample uses HTML email as content type.
- You can add email attachment to emailMessage.
- To send email and test the program, just change fromUser and fromUserEmailPassword. Yes it is as simple as that.
