Hack Smtp Server Backtrack


SMTP stands for ‘Simple Mail Transfer Protocol’ & this email communication protocol was designed for ‘functionality’ not for ‘security’. The SMTP is the part of ‘TCP/IP’ protocol, which utilizes a procedure called ‘store & forward’. The SMTP moves your email on & across the networks. It provides a bunch of codes that define the communication of email message between email servers & it is a type of ‘shorthand’ that permits a server to ‘break up’ different parts of a ‘message’ into the ‘categories’ the other ‘servers’ can understand.

• The attackers can verify whether ‘email account’ exist on a ‘server’ is simply to ‘Telnet’ to the server on port ‘25’ & run the ‘VRFY’ command. This command makes a ‘server’ to check whether a ‘user id’ exists or not. The ‘spammers’ automate this method to perform a ‘directory’ harvest attack, which is a way of obtaining valid email addresses from a server for hackers to utilize.
• The ‘scripting’ of this attack can test thousands of ‘email address’ couples or combinations. The command ‘EXPN’ allows or permits the attackers to verify ‘what mailing lists exist on a server’.
• You can simply or easily Telnet to your ‘email server’ on port ‘25’ & try ‘EXPN’ on your system.
• In ‘Net scan tools’, you can enter values for the ‘SMTP’ mail ‘server-name’, sending out the ‘domain-name’. Under the ‘test message’ settings, enter or type the ‘recipient email address’ & ‘sender’s email address’.
• At last, when the ‘test’ is complete or finish, then click on ‘view relay test results’.
