Can you give me a command that tests your theory? I tried nslookup on my IP address and it seemed to give a valid response. Same with my machine name. I don't think anything has really changed on the network. I've had this problem for a while off and on, though.
I am an English professor who has hobbied around with computers since
the early 1970s. I may not know what I am talking about, but I do
maintain a private and a separate public DNS that do proper RDNS for
their connected clients (few that they are).

If you could get a NOERROR reply from 'dig @yourDNS rcmac.llnl.gov' that
with an ANSWER SECTION having an IP that matches the one you are
assigned (134.9.94.100), then I believe that means your DNS is
configured to tell your computer your IP when queried by name and you
can use 'host IPRETURNEDBYDNS' to get something such as
100.94.9.134.in-addr.arpa domain name pointer rcmac.llnl.gov
or
100.94.9.134.in-addr.arpa domain name pointer rcmac
If this does not work, I believe that means you lack a valid RDNS. Your
mail header implies that you do not have an RDNS because the received
says
Received: from rcmac.llnl.gov ([134.9.94.100])
But I believe it should be
Received: from rcmac.llnl.gov (rcmac.llnl.gov [134.9.94.100])

Thanks for this information, if I can figure out what's wrong I will post my fix. I'm still working with the xemacs community to understand the issue. It hangs in getaddrinfo() and I cannot tell why this might be.
Has there been any changes recently in your network/firewall/dns? I've seen this problem with xemacs over the years (literally the first time I encountered it was 11 years ago), and it's always something to do with the network settings on the computer. Are you able to do a reverse look-up on your IP address for example, not being able to do that caused this issue for me back in the day.
