issue with email address

When I use the "officers @....." email address the email for the previous president Ron Watts continually bounces back. Yet, it is the correct address - the message I get says - ronwatts@picknowl.com.au was skipped because it has previously bounced too many times. If I email him directly there is no problem. What can be done? Wendy
