Topic: use foreign domain mailaddress - 550-Invalid authentication error

[fpausp]

I like to use a foreign (not my own domain) mailaddress on my server. When I try to send a mail with this address I get an error:

Code: [Select]

Hi. This is the qmail-send program at mydomain.at.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<target@targetdomain.at>:
127.0.0.1 does not like recipient.
Remote host said: 550-Invalid authentication (you can only send from @mydomain.at or its
550 aliases)
Giving up on 127.0.0.1.

--- Below this line is a copy of the message.

That's exactly how it should work. If not, I could use your domain to send email messages.

Yes... but I like to use more than one domain on one sme9 server to send and receive mails, how should I do it ?

Simply add domain in server-manager and make sure you OWN the (DNS) domain.
