Hi. This is the qmail-send program at server.myserver.com.
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.

Connected to 24.232.0.160 but sender was rejected.
Remote host said: 530 authentication required for mail submission

any idea how to fix ?

I still have this problem, is there a way to config sendmail to send some domain mails via another smtp server instead itself ?
thanks
