Get Error Message when sending emails with SBS 2003
Hello,When some clients try to sent an email the often get the following message: <sv01.test.local #5.7.1 smtp;554 5.7.1 This message has been blocked because the return email domain is invalid.(failed to obtain DNS record for domain test.be)>I already changed de FQDNS in my exchange server but this doesn't solve my problem. The strange thing is, when I try to send the email a few seconds later , it's sended.The IP in my public mx record, is the same as the IP of my WAN connection

It looks like you don't have all the required DNS entries for
your e-mail domain and/or server.-- Ed Crowley MVP"There are

Hello,
Is it also possible that it has something to do with licensing.
It is a SBS for 5 users, but 6 users are connected. But we have planned to do Licences CAL upgrade.
But can this be the reason for my problem ?
