Peace be upon you

I think a lot of people uses the SMTP wrong :D, why am I saying this, simple because every referance I have read about it was about simple tasks for the mail
nothing complex, I have never seen anyone talk about authintication in SMTP, anyways lets begin doing this cool thing , I will explain every step

Open Start -> Run
type Telnet

here it comes black screen -lets suppose that our mail server called SMTP.Ahmed-Essam.com -

let's begin in the black screen

U : o smtp.Ahmed-Essam.com 25
S : 220
U : HELO MyDomain
S :250
U:AUTH LOGIN
S:VXNlcm5hbWU6 in this point you will need a base 64 convertor http://makcoder.sourceforge.net/demo/base64.php
U: "your user name after encoding with base 64"

Peace be upon you

look my dear, I think this problem happen because you don't have paid subscribtion in yahoo, I read before that you have to buy the Yahoo plus package to get SMTP and POP3 access to your mail, also it is applied on Hotmail accounts, you should have Paid Live Mail, anyways, some Mail providers add their own addings to the SMTP Server they have

I hope that it is informative
