Subject: Re: what is "unable to fork" email err message means?

=> Unable to fork: temporary failure. (#4.3.0)
=> I'm not going to try again; this message has been in the queue too long.

	2. The box running the MTA on Yahoo's end has most likely run out of
PIDs (because its being DDoS'ed?) and cannot "fork()" any children processes
(see /usr/src/linux/README) to go out and deliver mails to each recipient,
and hence bitches, and returns mail back to sender.
