I am using Java mail API to send emails. I have installed SMTP server on my system.
So in Java class, I am setting the property "mail.smtp.host" as "127.0..0.1".
The email id to which I am sending emails is "email@example.com". In the "from" field the email id being set is "firstname.lastname@example.org". The emails are send perfectly fine.
Now I changed the from email address to "email@example.com" (the domain for "to" and "from" is the same). Now the emails have stopped going. In other words, whenever I change the domain of "from" address to be different from the domain of "to" address the emails go fine. As soon as I give the same domain ("tes" in this case) for both "to" and "from" email address the emails stop going. Can someone please let me know why this problem? Is this a SMTP restriction or Java mail restriction?
