Sendmail spam solution (?)
I have an error messages recieved by Mailer Daemon.
The original message was received at Fri, 29 Aug 2003 10:34:56 +0500
from localhost
with id h7T5YuMB013812
----- The following addresses had permanent fatal errors -----
<cgqinu@yahoo.com>
(reason: 553 VS10-RT Possible forgery or deactivated due to abuse (#5.1.1))
----- Transcript of session follows -----
... while talking to mx2.mail.yahoo.com.:
>>> DATA
<<< 553 VS10-RT Possible forgery or deactivated due to abuse (#5.1.1)
550 5.1.1 <cgqinu@yahoo.com>... User unknown
<<< 504 At least one RCPT command is required
Some nodes sent uncorrect messages (spam) to my host for delivering to other hosts (in this case to yahoo.com).
How could I make changes in sendmail configuration file to deny any mail requests from other hosts exlude my?
other info:
My node is firewall to the internet for local network.
ESMTP Sendmail 8.12.4/8.12.4
Thank you.
