[SOLVED] question about reverse records

[coper]

Hello,
I was checking my bind configuration because some emails not reaching destination.
I checked the dns settings on various websites and results show me that I have PTR records for all my ips. Look this example from intodns.com (assuming that my server is called myserver):

Code:

Reverse MX A records (PTR) Your reverse (PTR) record:
X.XXX.XXX.XXX.in-addr.arpa ->  myserver1.domain.com
You have reverse (PTR) records for all your IPs, that is a good thing.

Why show me myserver1.domain.com if my servername is myserver?
Where is it configured that name?
In /etc/hostname I have "myserver"
And in /etc/ispcp/ispcp.conf I have
SERVER_HOSTNAME = myserver.domain.com

The question is where is "myserver1"?

I read the following in some post about PTR records:
Maybe we'll bring ispcp to do that too :-) - but this has less priority...
I think this shouldn't be less priority, lots of clients have problems with emails not reaching destination. It's just a sugestion.

Thanks for any help!
