What does this error message mean?

You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <mail.companywebsite.com #5.7.1 smtp;554 5.7.1 The server sending your mail [xx.xxx.xx.197] does not have a reverse DNS entry. Connection Rejected. Please contact your Dial-Up/DSL/Network ISP Provider. Default Reject!>

Does it mean there is no reverse DNS entry for this company's main domain or no reverse DNS entry for something else? Also, where does the reverse DNS entry need to be created, in the sending company's DNS server(s) or someone else's DNS server? Thanks.

can you tell us a little bit more about your setup?  Do you send mail through your IPS's mail server or do you have your own mail server?

Did you get this error when you tried to send an email to someone else, or did someone else get this error when they tring to send you email?

In either case i would go to www.dnsreport.com and do a test of yourdomainname.com to make sure your domain's DNS is set up correctly.

I just found out that one of my coworkers had made some significant changes to this clien't WAN settings with their ISP but didn't tell me jack about it. I can't wait to never have to work with humans again! :)
