Club email list stopped delivering emails

Our club email address has stopped delivering emails since 3/27. I and another member have correctly sent emails to our club email address as usual, and nothing happens. Please advise. 

Please make sure that your DNS settings are set up as per the instructions here:  support.toastmastersclubs.org/doc/item/dns-settings-overview
Your mail record is wrong, please check the others too. 

I'm not too tech savvy but I've read all instructions, checked links, and don't see anything amiss. What do you mean by "Your mail record is wrong?" TX!
