Hello,
I am getting the following error when sending to the below mail server. I
added the name of our internal relay server to our public dns and a ptr
record, but I am still getting the error below.
<snip>
host mxi4p.craigslist.org[208.82.236.164]
said: 554 5.7.1 <unknown[207.47.100.34]>: Client host rejected: rDNS/DNS
validation failed. Please setup matching DNS and rDNS records:(in reply
to RCPT TO command)

Is there something else I need to add the postfix server? This is an
internal mail relay server, behind a firewall and not accessible to the
public. It only sends mail for our internal users and does not receive mail.
Many thanks,
James
