501 Domain must resolve
Posted on 2013-11-19
Have a problem with email, where if I do not route our exchange mail through our ISP's smart host then a certain domain wont allow our email (genzone.net).
I simply cannot route the mail through the smart host though, because we get loads of bouce backs again because its sees to much of our mail as spam due a CMAE Filter, BTW my ISP is DEMON, and this isn't happening to just me.
I cannot see my current mx record though.
Is the reason why my messages are being blocked by genzone.net because I haven't got an MX Record?
