I am using exchange 07 but we still rout our mail through a 3rd party (network solutions) so we have an SMTP connector and POP3 for incomming. I am also getting this error on some emails. When I do the nslookup comand it times out as well. parrishconstruction.com is our domain. Our mx record was setup as mail.parrishconstruction.com so I have the reverse lookup set as that with our ISP. When the email leaves our office the header most have our exchange server in the ID and then I don't know what happens to it at Network solutions. I would assume the reverse of mail.parrishconstruction.com sould resolve the reverse DNS but we still have problems at times? I am somewhat new to this stuf so I am not sure what else to look at. Thanks! Running exchange 07
