Disable UUCP headers

[smikes19]

Hi,
I need to protect my sendmail 8.9 server against 3rd party relays. Orbz.org used a particular smtp envelope that let it slip through and allowed to be relayed. I was told this was a UUCP header. How do I disable UUCP headers in sendmail 8.9 running on solaris 8???

Thanks!

Edit sendmail.mc and add this line:

undefine(`UUCP_RELAY')dnl

Then:

m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

Then restart sendmail

Can I just comment this line out of the sendmail.cf????


R< $+ ! > $+ $: $1 ! $2 < @ $Y > use UUCP_RELAY

Ok I've changed up the .mc file and added in:

FEATURE(nouucp)dnl
undefine(`UUCP_RELAY')dnl

I ran a make, replaced sendmail.cf, restarted the daemon...and still no go...these envelopes still get relayed..

:Relay test: #Test 17
>>> mail from: <spamtest@[63.xxxxx]>
<<< 250 <spamtest@[63.xxxxxxxxxx]>... Sender ok
>>> rcpt to: <mail-abuse.org!nobody>
<<< 250 <mail-abuse.org!nobody>... Recipient ok
>>> QUIT

Hi smikes,
I'm not quite sure what the problem is. I'm using the version of sendmail that came with Red Hat 7.1 and it comes out of the box not allowing relaying. I have to specify who I will allow to relay through my server. I also had to do an upgrade recently because of a security problem with sendmail allowing hackers to gain root access to the server and relay spam through it. You might make sure you have the latest version from

http://www.sendmail.org.

Sorry I couldn't help you.
