Wietse,
You were 100% right -- it was the DNS that was screwed up! Somehow,
balka.com had a DNS entry on that hosting facility, when it shouldn't.
Now the email goes through.
Thank you so much for your help. I'm having another small problem which
I'll post under a separate thread.
Best regards,
Marcelo
