I think that Sky have more than one email server/mirror. Try doing an
nslookup on '74.125.127.208', on my PC it came back as
'pz-inf208.1e100.net'. Or if on another day you get yet another ip address
returned by nslookup on 'bskyb-pop3-ssl.l.google.com', feed that ip into
nslookup and see what comes back. I bet you it won't be
'bskyb-pop3-ssl.l.google.com'.

"Correctly"?
$ host bskyb-pop3-ssl.l.google.com
bskyb-pop3-ssl.l.google.com has address 74.125.127.208
Doesn't look like 216.239.59.208 to me. Do you have "host" on your machine?
If so, what does it resolve bskyb-pop3-ssl.l.google.com to? And what do you
get for "host -a 216.239.59.208", "host -a gv-in-f208.1e100.net", and "host
-a bskyb-pop3-ssl.l.google.com"?
