Problem with sendmail

[HawkY <hawky@freemail.hu>]

Hi!

I've got a problem with my sendmail. It does not send mails through my 
dial-up connections but does deliver my local mail.
In /var/log/mail/mail.info I've found something I don't understand:

Jan 16 17:44:31 debian sendmail[331]: XAA01148: to=hawky@freemail.hu, 
ctladdr=hawky
(1000/1000), delay=18:32:37, xdelay=00:00:00, mailer=relay, 
relay=fmx1.freemail.hu.,
stat=Deferred: Name server: fmx1.freemail.hu.: host name lookup failure
                                          ^^^^^^^^^^^^^^^^^^^
What is that "fmx1" thing? (I found lines with "fmx2" and "fmx3" in 
mail.info too.)

How can I make sendmail to work?

Thanx, Balazs
