Hi,
Lately I've been getting some bounced mail from people at the
provider/server plus.com. I've redacted addresses, but this is the error
message:
<<< 550 #5.1.8 Domain of sender address <xxxxxxx-boun...@xxxxxxx.com>
does not exist
554 5.0.0 Service unavailable
Obviously, the sending domain *does* exist, so I assume it's their
problem. Is there anything at all I can do about this? Not all mail to
these users bounces.
Thanks,
Jayson
