When I try to make an appointment, I give the basic details and add some attendees. Everything works fine. The appointment appears in the person who made the appointment. But the attendees don't get any email. When I save the appointment, I get an error:
Invite not sent, one or more addresses were not accepted. Rejected addresses: Shikha Sood <shikha.sood@hostname>
I looked up some threads some people suggest that the DNS setting should be proper.
The MX records in my etc/hosts file as follows:
@ MX 5 mail.yourdomain.com
You'll also want to set up an "A" record for the "mail" host on "yourdomain.com" that points to your external IP address.
mail A 18.104.22.168
But it not makes any difference.
Also, when I try to send/receive mails, though it says "message sent" no message appears in the recipientís inbox
Don't know whats the problem.PLease suggest
