SMTP authentication problem

[pongzaa]

I checked my server, it's not open relay mail.
But my server can send email with no authentication.

Spammer can use my server send lots of email.
How to resolve this problem? What i config wrong.

Thank you.

Are you using the standard exim.conf file supplied with DirectAdmin? By default it won't allow open relay.

If you've made changes, you're on your own or you may need to hire someone to check your server.

If you haven't made any changes to that file you should make sure that no domain hosted on your server is listed in the /etc/virtual/whitelist_domains file, as that could turn your server into an open relay for anyone posting with a from address of one of those domains.

I resolved this.

da-popb4smtp shouldn't work after dovecot intalled.
I stop da-popb4smtp and clear IP in /etc/virtual/pophosts

Everything go fine.
SMTP must give authentication always.

I confused why popb4smtp works. Can i disable it?

I'm not sure why popb4smtp shouldn't work after Dovecot is installed, though that certainly may be the case.

If Dovecot is populating the pophosts file, then it should work as it used to.

Of course if the popb4smtp daemon isn't running, then pophosts shouldn't be repopulated.

Check to make sure that the daemon isn't running.
