Default SPF and reverse DNS for mail

Hi all,

I start one thread for 2 problems I have at the moment. But the problems must be looked at together.

First problem:

I have set my mail-server to be reachable at mail.mydomain.dom. But when I do a reverse lookup of the IP, I get ns.mydomain.dom. Could be a problem with some mailservers.

How can I set the reverse-zone of bind, to bring mail.mydomain.dom when I do a reverse lookup? Or better, how do I set it in ISPconfig? The zone-file is generated from ISPconfig, so if I change it by hand, it will be overwritten when I do changes in ISPconfig.

My reverse-zone-file looks like this:
Code:
$TTL        86400
@               IN      SOA     ns.mydomain.dom. hostmaster.mydomain.dom. (
                                2005111601       ; serial, todays date + todays serial #
                                28800   ; Refresh
                                7200    ; Retry
                                604800  ; Expire
                                86400)  ; Minimum TTL
                        NS      ns.mydomain.dom.
                        NS      ns2.mydomain.dom.
22       PTR     mydomain.dom.
22       PTR     www.mydomain.dom.
22       PTR     secure.mydomain.dom.
22       PTR     mail.mydomain.dom.
22       PTR     ns.mydomain.dom.
22       PTR     ftp.mydomain.dom.
22       PTR     subdomain.mydomain.dom.

;;;; MAKE MANUAL ENTRIES BELOW THIS LINE! ;;;;
Second problem:

How do I use the SPF records in the right way? I have not found a description in the manuals. What to set as hostname (should this be mail?)? And what are all the other things?

I think for this to work, I need to resolve the first problem.
