530 - Authentication required (sending mail)

Hi,

I'm currently using Mdaemon mail server v11.
I'm trying to create my own outgoing mail server.

Sometimes sending mail is going great.
Other time (other computers) have a 530 - Authentication required error.
How can I fix this that when using my outgoing mail server you can send mail to who ever you want.

There is nothing going through my SMTP OUT. Is this normal?

This is my log (SMTP IN).

To prevent relaying, which you don't want, the sender needs to
authenticate with a local account (an account hosted on your MDaemon
server) before sending mail. There are typically settings to do this in
the SMTP configuration of the client. Assuming *****@mighty.eu.com is
an account in a secondary domain, configure the client to login when
sending using the credentials from that account. Without
authentication, anyone could send mail through your server quickly
getting you on spammer lists.

As an addendum to the excellent recommendation from Jay (you really do want to require authentication so you don't have problems with spammers or other malicious people), the reason the authentication prompt was occuring is that the user was sending into the server with the MSA port (port 587) which always requires that the user authenticates in order to send mail via that port. Your other users who were not being refused were most likely using port 25 instead.
