One of my domains is having intermitant mailer-daemon falures. the folowing are all the messages from different domains he's emailed. I have 300+ domains and this is the only one with the problem. I checked my Bind DNS servers/entries and all is good. I published PTR records also - the only thing I can think is maybe domainkeys or DKIM? but sometimes the mail will deliver. weird.
any advice so appreciated!
