Postfix - 554 Transaction failed (in reply to MAIL FROM command)

I am running a small website using PHPNuke. I have been having issues with New Users receiving the registration email from my site. I found out that I didn't have sendmail or post fix installed correctly. After trying unsuccessfully with sendmail, I decided to try Postfix. After installing postfix. I find that some people are receiving the email, while many do not.

I am getting MAILER-DAEMON return messages now: Here is the results from it:

This is the Postfix program at host localhost.

I'm sorry to have to inform you that the message returned
below could not be delivered to one or more destinations.

For further assistance, please send mail to <postmaster>

If you do so, please include this problem report. You can
delete your own text from the message returned below.

The Postfix program

I am not sure what I am doing wrong, but obviously I am doing something wrong.

I have Webmin, using Mandrake 9.2, I have a linksys router, Dynamic IP, using services for Dynamic IP issues, Postfix, and using PHPNuke 6.9, if any of this matters.

Please if you have any incite on this issue I am having, please do explain to me. I have done many Google searches for the last month, and because I have come up empty from my searching, I have decided to post my issue here.

I am stuck,

Tell people not to register with a Hotmail, MSN, AOL, or Yahoo addresses to sign up. Those networks don't accept mail from IPs in dynamically assigned netblocks or from IPs without reverse DNS entries. It seems the large carriers have decided to "solve" the spam problem by censoring a huge portion of the IPs currently assigned.
