PTR setup correctly?
 

hi all,

how can I verify, that PTR entry (reverseDNS) for mailserver is setup correctly??
is a

#dig -x <ip.address>

sufficient, if there comes an ANSWER-section back?

yes, or just do an nslookup <IP address> and see if it responds

yes, but my current problem is, that PTR seems to be correct, but AOL´s rDNS-check "kicks" my emails!
<dig -x ip> shows

;; ANSWER SECTION:
xxx.xxx.xxx.xx.in-addr.arpa. 93599 IN PTR host.domain.tld

which is correct! so what is wrong, PTR entry from ISP or mailserver-setup ???

hope someone can help..............

Make sure that the hostname in your mail server greeting matches your host.domain.tld

I would recommend doing a test at http://www.dnsreport.com

thx, but it´s all correct!
...found out, that it must have something to do with the smtp-headers ´X-Mailer´ and/or ´X-Authentication´.
seems to work now, hmm, will have an eye on it........

any further ideas,tipps,.....welcome ;-)

hi guys,
today the same old shit.

again not working with or without headers_removed!
what does a mailserver check when he do a rDNS??
smtp-headers? only if a ptr exists....for what, domain-name?
