Hi Mark,
Thank you for your reply.
Yes, we are using Zoneedit email forwarding. We get emails to our server and then server sends emails to every PC.
Yes, there are many possibilities to cause the email problems. I am trying to find out the real one. Quick response is very important for me now. But Zoneedit is really letting me down.
My company domain is decorso.com.au.
I tried to use the office email to sign up in Zoneedit forum and then you can see my domain, but it cannot receive the confirmation letter. This is exactly the problem I am facing now. Out emails are very picky now for unknown reasons. It cannot receive the emails from Hotmail.com and Zoneedit confirmation letter, or the emails with attachments. But it can receive emails without attachments and emails from Zoneedit support. And the "support"ZoneEdit only tells me go to here regardless what questions I faced.
Best Regards,
Dorothy
