Today's winner of the amusing hostname prize is '
GE-queer-A.gay.it
' aka '
server1-gay-it.it.net
', which is what the IP address 151.1.32.3 currently claims to be in SMTP (the first name) and its PTR records (the second name; there is no matching A record).
I do have to wonder what sort of naming scheme gave rise to this. (It has neighbors with different 'serverN' PTRs, so it's not just one machine.)
