[cobalt-users] 501 Mail Error.

["Jimmy Gross" <jimmy@xxxxxxxxxxxxxxx>]

Any idea on what this error means and how to fix it? I can send email to anyone except people in our domain: constantino.net.

 

Hi. This is the qmail-send program at phnxpop4.phnx.uswest.net.

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.

<jimmy@xxxxxxxxxxxxxxx>:

Connected to 207.254.34.194 but sender was rejected.

Remote host said: 501 <jimmy@xxxxxxxxxxxxxxx>... Sender domain must exist
