Hello.
I am receiving messages since fake account of my domain, by example [email protected] [email protected], [email protected], etc.
Testing by telnet mail.mydomain.com i verified that can send using fake account to other servers how Gmail account.
I have not modified anything in exim.
How to avoid sent using false accounts from my domain?
I test my mail server with http://www.abuse.net/relay.html and it indicates to me
Relay test 6
>>> RSET
<<< 250 Reset OK
>>> MAIL FROM:<[email protected]>
<<< 250 OK
>>> RCPT TO:<securitytest%[email protected]>
<<< 250 Accepted
Relay test result
Hmmn, at first glance, host appeared to accept a message for relay
Thanks.
