we have an address jobs@supportforfamilies.org that receives mail all the time but yesterday this bounced from someone:

From: Mail Delivery System <Mailer-Daemon@elasmtp-banded.atl.sa.earthlink.net>

Was it the only one to bounce? Did he try it again after that and get the same message?

It sounds like an anti-spam tactic. I am not sure what edge transport server / hosted solution you are using but many of them have a list of ligitimate recipients (some sync with AD, some are manual imports), and if an address is not on the list the system assumes it is spam and bouces it or drops it. Do you know if anything has been updated latley? You might want to check.

This suggests to me that no-ip.com have dropped your address. try contacting them.

As I understand it, no-ip.com offer a forwarding service that appears to have (temporarily?) failed.
