Club 3972 emails to group lists are not going thru

I reported an issue a few weeks ago about my emails not going thru to the members & officers list.
You had requested my IP address.  It is 76.14.61.197.
Starting this week, I am also not receiving emails from the list.
This is the last error message I received:
