geoip is not perfect, but a glance at your mail headers suggest that there
may be some confusion from another source.

IPs, rev names and time zones seem to match. The machine you sent the mail
from seems to be definitely in Japan, and geoip says so as well. The mail
server, mort.cihar.com, looks Czechish (per its time zone and your name) --
again, geoip confirms that.
Assuming all machines use a nearby DNS, could you check again, using
"nslookup" or similar to avoid http proxies? Travelling/sshing to the other
side of the world means you may use a resolver all the way at home.
