FTH email relay (fails for specific user)

I'm VP Ed, and I have no problems sending or receiving emails via FTH (members-xxx, officers-xxx).  Our club president is having problems just in the last couple of days. We're both on Gmail, and I don't know how to isolate the problem further.  President can neither send or receive.  Yet she can send to me directly.  

Do you keep logs of email activity? 

Thanks.

A recent change in gmail behavior caused an issue with FTH that has been resolved.

Some (but not all) gmail users were affected including your president. She needs to log into her account (using her name) and restore her email address.

Please go to your site and look in the membership management panel and fix your presidents email.
