open relay server?

[whitelionweb]

Ok recently i have found that my server is a open relay server and when i try this to ANY other server such as my friend etc none of them have the same issue, i am running the same config as them and still same issue

When i go into port 25 via telnet i am able to send emails to ANYONE via my server and it can be from anyone ...

All i type is:

helo
helo
Mail from: [email protected]
RCPT TO: [email protected]
DATA
TO: [email protected] <[email protected]>
From: [email protected] <[email protected]>
Subject: test email
My message here

.


This allows me to pass through spam filters as it comes from my server ... not me or a php script it works on a few webhosts but others reuqire you to authenticate... How do i make this so on my server?

Are you currently / have you recently logged into a mailbox on the server? If so you may well be being allowed to send mail through "pop before smtp" auth.

Check the exim log and for your IP in /etc/relayhosts

Hello,

Try the following command which will disable pop before SMTP and enforce SMTP auth.

/usr/local/cpanel/bin/tailwatchd --disable=Cpanel::TailWatch::Antirelayd

restart exim

Then check openrelay at Email Server Test - Online SMTP diagnostics tool - MxToolbox

Thank you.
