[Ishan]

my friend can send me/anyone an e-mail from any e-mail address
eg.
my id: my_id@gmail.com
his id: his_id@gmail.com
someone else's id: someoneelse@yahoo.com



then he(his_id@gmail.com) can send me mails which shows:
from: someoneelse@yahoo.com
to: my_id@gmail.com
subject: he can write anything
message:he can write anything

--------------------

Your Friend is sending Mail using PHP Mail() Function

It lets you send mail with any name in "From" Field. For example - "billgates@microsoft.com".

This is how Phishing Mails work. They seem real since the From Field looks official like "HDFC Bank", "Paypal" etc.

Well, there is no way you can stop him or anyone on the net. Only way is to check the headers of the mail and see if the MAIL is actually originating from the official servers

PHP MAIL Sample

<?php $to = "someone@example.com";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "someonelse@example.com";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent."; ?>

also some of his mails were going in SPAM, so he told me the reason that some of his server or IIS(which i took as Internet Information Services) settings are not proper thats why..

Big Email Providers such as Yahoo, MSN, GMAIL have filters to detect such mails and put them into SPAM

If it's coming from gmail/yahoo, where does his server come in between. And what has IIS have to do with mail? AFAIK, IIS is a http server not a mail server.

IIS is a web server dude!! it comes with SMTP service also!! so u can send mail using it...just few line of asp, c# code+IIS...bingo!
actually i love Java+tomcat for this kind of prank with my friends...in the 'from' field U CAN CHOOSE THE DOMAIN NAME WHATEVER U WANT...just follow the convention...it's a funny thing
p.s- there is no e-mai hack dude!

I didn't know about this since I have never used IIS.

Oh..I wish I could change the subject of this post then............Thanks for relieving me from tension.....

But its bad thing that i cant stop him coz he sends bad mails to my dad using my id..
Fortunately my dad forgot his e-mail account password...and he(friend) doesn't know this....So i recovered the password and deleted the mails too... So Thanks to God too!

But there is Future Risk too!

Ok I wont ask how its done coz u'll say its illegal here (nice indirect way huh?)...but plz if anyone comes to know how it can be stopped............PLZ INFORM ME...PLEASE PLEASE PLEASE

Don't let ur friend use computer!

Frankly saying, this can't be stopped. Bcoz till he has access to computer n Internet he CAN send such mails.

One thing, you can do it tell him that u knows how to send such mails. And if u send such mails again by my name, then I can do the same with you too.
And finally file a complaint against him in Cyber Police!

[Pathik]

Or you can do the same to him. And you can check the mail headers to ascertain the sources.
