Member email bouncing and not receiving

Emails to my primary email address stopped being delivered. I changed the email in FTH to an alternate address that worked, and when I tried to change it back I got the message

Invalid/Non-functioning E-mail: <redacted> (No advertised SMTP servers are accepting mail.)

We also have another member with a gmail.com address that receives test emails from FTH but not the agendas.

Is there any sort of email log that I can check?

thanks in advance
Brett.
