OLD HACK

Postby xosa » Wed Oct 17, 2018 7:40 am

I have a genereal question.
Why default Zimbra installation have old hack problem ?
If attacker know a proper mail account can send mails unverified to local domains.

Example :

telnet mail.example.com 25
helo ala.local
mail.from: <ala@example.com>
rcpt to: <ala@example.com>
data
test
.
quit

Now in Poland there is an attack based on this hack
