If I were in a bad mood I'd see some poetry in that.
Instead, I'll say that I think we have removed their stuff from our
sendmail.cf files.
But there are no doubt others in our address space that I don't know
about.
So.
Somebody send me the IP addresses of their servers, I'll spend a couple
of ACL slots and block-and-log accesses to their servers to protect them
and to identify folk here that need to be told.
Yes, I know I could look them up.
After dinner I might.
