Relaying denied

[saitan]

I can get and send mails but only if i send them via telnet or if i'm in front of the server.
i can't use outlook explress for example.
the server always tells me:

550 5.7.1 <the address>... Relaying denied. IP name lookup failed [192.168.0.10]

at the moment, I'm using a web-mail-client.. this works.
is this maybe a kind of 'hacking-protection'? and what can I do?

Hi
add ur address 192.168.0.10 to the file /etc/mail/access & then run :
makemap hash /etc/mail/access.db < /etc/mail/access
