    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: test@test.com
    RCPT TO: person@person.com
    DATA
    TO: test@test.com <person@person.com>
    From: test@test.com <test@test.com>
    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
