I have a problem with sending e-mail to a mail adres on versatel.nl, I get the following error:
rblsmtpd.local #553 We do not accept mail from IP addresses without reverse DNS. See http://wikipedia.org/wiki/reverse_dns
My DNS is:
mail.ourdomain.com A 1xx.2xx.156.4
ourdomain.com MX 10 ourdomain.com.pri-mx.eu010
ourdomain.com MX 90 ourdomain.com.bak-mx.eu010
The mail go's to our hosted SPAM filter and from that it's send to our mail server. The e-mail get send out directly from our mail server. if I go to MXtoolbox.com I get the following information:
Not an open relay.
0 seconds - Good on Connection time
9.173 seconds - Not good! on Transaction time
OK - 126.96.36.199 resolves to gmy1-mh542.smtproutes.com
OK - Reverse DNS matches SMTP Banner
What am I doing wrong?
