Most of us are very curious to know a method to send anonymous emails to our friends for fun. But the question is, is it possible to send anonymous emails in spite of the advanced spam filtering technology adopted by email service provides like Gmail, Yahoo etc? The answer is YES, it is still possible to bypass their spam filters and send anonymous emails to your friends. For example, you can send an email to your friend with the following sender details.


The art of sending this kind emails is known as Email Spoofing. In my previous post on How to Send Fake Email I insisted on using your own SMTP server to send anonymous emails. This method used to work successfully in the past, but today it has a very low success rate since Gmail and Yahoo(all major email service providers) blocks the emails that are sent directly from a PC. In this post I have come up with a new way to send anonymous emails (spoofed emails) that has 100% success rate. If you have to successfully send an anonymous email or spoofed email, you should send it using a relay server.
What is a Relay Server?
In simple words, a relay server is an SMTP Server that is trusted by Google or Yahoo as an authorised sender of the email. So, when you send an email using a relay server, the email service providers like Yahoo and Gmail blindly accept the emails and deliver it to the inbox of the recipient. If the SMTP server is not authorised, Google and Yahoo will reject all the emails sent from this SMTP server. This is the reason for which using our own SMTP server to send emails fail.
So What’s Next?
Now all we have to do is, find a trusted SMTP server to Send Spoofed Emails. Usually all the emails that are sent from web hosting providers are trusted and authorised. So, you have to find a free web hosting provider that allows you to send emails. But, most of the free Web Hosts disable the Mail feature and do not allow the users to send emails. This is done just to avoid spamming. However all the paid hosting plans allow you to send any number of emails. Once you find a hosting service that allows to send emails from their servers, it’s just a cakewalk to send anonymous emails. All we have to do is just modify the email headers to insert the spoofed From address field into it.
I have created a PHP script that allows you to send emails from any name and email address of your choice. Here is a step-by-step procedure to setup your own Anonymous Email Sender Script
