Exchange 2007 outbound mail error

We have had some emails bounce back with the following error:

An error occurred while trying to deliver this message to the recipient's e-mail address. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.

The following organization rejected your message: rblsmtpd.local.

Trying to troubleshoot and there seem to be no PTR records set up for our mail server online.  My question is this.  Will not having the PTR record(s) set up cause this particular problem?  From what I have been able to gather, if the recipient's mail server does a reverse DNS on an incoming message and there is no PTR record, then they will reject the message with this error.  Please let me know I am understanding this correctly.

" rblsmtpd.local" it looks more like you are blacklisted

I ran our ip addresses on some blacklist check sites and they came back clean.

You understand correctly. Not having PTR for MX record can cause mails being rejected.

if you are not blacklisted than yes the issue is probably a missing PTR
