DNS reports: mail connect error

[fossie]

Hello,

System:
CentOS 5.1
DA: 1.31.5
domain: host01.be: ns1.host01.be(195.207.16.76) and ns2.host01.be (195.207.16.77)

I've just setup a new server and was just testing a bit:
I found a (few) problem(s) with : http://www.dnscolos.com/ (erros below)
and (except from rDNS) no errors on: http://www.intodns.com/

dnscolos: (errors - red)
Failed Parent nameservers host01.be Your NS records at the parent server are:
Failed Nameservers for domain in DNS host01.be Your NS records at your nameservers are:
----
Failed Mailserver connection test
HELO, MAIL FROM, RCPT TO, QUIT Connect to mailserver mail.host01.be FAILED (could be greylisting)
----
Failed Mailserver greeting The server should have an A record which points to the mailserver for the hostname
which is presented in the greeting

mail.host01.be
----

The thing is, I can sent mail, I can nslookup the server, does someone know what could be wrong in the configuration?

Maybe another test page where I can compare the results?

TIA,
Fossie

The rDNS records are up to date and working, but at dnscolor.com I still get an error:
Failed Mailserver connection test
HELO, MAIL FROM, RCPT TO, QUIT
and the
Failed Mailserver greeting

Someone can help me with this?

TIA,
Fossie
