Currently I am using a sendmail pop3 server for email. We have setup a zimbra server and are planning on migrating to it. Right now the sendmail server is setup as @bussiness.net and the zimbra server is setup to receive mail for @bussiness.com. The zimbra server is able to receive and send email externally but when I send an email from my sendmail server it gets returned.
It says: Host unknown (Name server: business.com: host not found).
Also when I try sending from the zimbra server to the sendmail server it gets returned saying:
Host or domain name not found. Name service
error for name=business.net type=A: Host found but no data record of
All of the entries are made in the dns server. Am I missing something in the configuration? Thanks.
