<p class=MsoNormal><font face="Arial, Helvetica, sans-serif" size="2">Welcome
to yet another Hacking Truths manual. Although this manual comes after a long
break, it is really nice to get back to writing for HT. Anyway, in the past,
we have had a number of explanations on how to send forged emails, how to
play with the Sendmail daemon, email headers and everything else to do with
SMTP (Simple Mail Transfer Protocol) and emails. Although this manual too
throws light on related matter, it is however more focused on advanced tips
and tricks and other uncommon but extremely useful pieces of information.</font></p>

<p class=MsoNormal><font face="Arial, Helvetica, sans-serif" size="2">Now, we
have already learnt how one can, telnet to Port 25 of a mail server and send
an email (even a forged email) by simply typing out some SMTP commands. However,
for the benefit of beginners and to refresh the memory of experienced but
forgetful people, we would quickly be going through the process. I promise
to make it as short as possible, at the same time easy to understand.</font></p>

<p class=MsoNormal><font face="Arial, Helvetica, sans-serif" size="2">Port 25
is the Sendmail Port where the SMTP daemon runs. This daemon is infact the
daemon handling all the outgoing mails. All email clients send mail by connecting
to Port 25 of the mail server and issuing SMTP commands. This process is automated
and occurs in the background. However, one could also manually connect (telnet)
to Port 25 of a mail server and manually type out the SMTP commands in order
to send emails. So the basic outline of the entire process as below. For details
regarding the usage of individual commands, simply type the word 慼elp⌨️ 快捷键说明
