[cobalt-users] RaQ4: problem with the dispatch of e-mails

["Herbert Malle" <cobalt@xxxxxxxxx>]

Hi !

I have a problem with the dispatch of e-mails.
I can send messages away by e-mail only to the domains, which I created at
the cobalt.

If I try to transmit however the message to a distant domain, I receive this
error message:
###
The message could not be transmitted, since one was not accepted the
recipient
by the server. The not accepted e-mail address is ' hmalle@xxxxxxxxxxxxxxx
'.
Concern ' ', account: server ' mail.malle.at ': log ' mail.malle.at ': Smtp,
server
response: ' 550 5,7,1... Relaying < hmalle@xxxxxxxxxxxxxxx > denied.
IP name lookup failed [ 62,46,75,209 ] ', link: 25, Secure(SSL): No, server
errors: 550,
error number: 0x800CCC79
###

Why doesn't the dispatch function to other e-mail addresses?
Can someone help me?

Thanks !

Herbert
Note: I test my mailbox naturally before the dispatch of the message, in
order to open the mailserver.
