One of my customers has just been told he needs to pay to get a DNS
reverse map entry for thei Green ADSL line with fixed IP.
Is that really true??

If the reverse mapping points to some valid A record, why
do you need to change it?
There aren't many applications that really depend on the reverse name -
for most of the things it's enough that the reverse name is a valid one.

You never tried to operate a mailserver behind a DSL-connection yet,

well, I used to support customers which were running mail servers
behind a broadband connection. Most spam filters and blacklists like SORBS
check the reverse naming, and if it doesn't have words like cable, ppp, dynamic
and such, it's quite safe to work with it.
It just has to have some decent

In this case, the reverse lookup returns something like
zux000-nnn-nnn.adsl.green.ch.
The customer is (quite reasonably) running a mailserver on it, and would

We had asked several time green.ch for a delegation for a MPS8 and MPS16
contract - and they denied it. So submitted a list of
hosts to be added to their DNS for adding PTRs. No reply, and still only the
default PTR entries...
Has anything changed in this since the TIC merger?

That was reason enough for me to change provider.
There are other ISPs on this list which are RIPE compliant, less arrogant and

compromised.
