Hi,
I've developed a problem sending mail. I'm sending it to my account on my ISP, and it's barfing. Of course, I can still relay mail via my ISP, so I'm stumped. Well, I'm mainly stupmed at come it is sending from "machine.localdomain" rather than from "machine.mydomain". If I could work that out... Anyway, here's a failure message, domain names and so on redacted: -------------------------------------------------------------------- This is the mail system at host machine.localdomain. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message. The mail system <username@isp.domain>: host mx.isp.domain[a.b.c.d] said: 550 5.7.1 <user@machine.localdomain>...
