Thank you---I appreciate that!  The domain is antartida.xyz.  So I
deleted the a-record again.  Now we have:

%host -t a antartida.xyz
antartida.xyz has no A record

%host -t mx antartida.xyz
antartida.xyz mail is handled by 10 mx.antartida.xyz.

%host -t a mx.antartida.xyz
mx.antartida.xyz has address 195.88.57.140

%host -t ptr 195.88.57.140
140.57.88.195.in-addr.arpa domain name pointer mx.antartida.xyz.

What do I see now?  I see I was confused before because I *am* getting
e-mails from Gmail.  What stopped working for me is my IMAP client that
for some reason is not seeing the messages arrive after I deleted the
a-record of antartida.xyz, but then I tried another client and it sees
them all, so it's a client (Gnus) configuration issue.  (That's another
investigation I need to make, but it's not important.)  I apologize for
the confusion.
