[SOLVED] Can send external but not send/recieve internal email
Hi, I'm new to this and I have been giving a task on setting up email on Zimbra using Fedora 7. I got Fedora and Zimbra installed correctly and have successfully sent out emails to an external email address.
When I try to reply back I get "undelivered mail returned to sender." When I try to create a new email from an external accountand send it off from my test account I get "The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator."
I also have not been getting any response when attempting to send emails internally. I'm gonna need some major help and Thanks to everyone in advanced.
