I have been told that is an almost impossible task at some places
(countries). We can easily get a domain name, but we can not change the
reverse name: it is defined by the provider to his liking (read: less
work). Some providers here do not even have rDNS on!

How about setting myhostname? Mmm, it would affect receiving mail, I
suppose... And having both names, the one provided by isp, and the
contracted DNS name? I'm afraid I'm not too clear O:-)

Do you know that many providers in my country reject relaying mail if the
from address is not in their domain, even for clients in their network?
