Hi all, this needs a little explanation. We have an internal email server setup in house (Mdaemon 9.6.6). We send mail through that server but receive mail through our ISP provider which has the domain name. Everything works fine until we try to send mail to each other ie. paul@ourdomain to email@example.com. When you send an email like this it seems to go just fine as I watch the server session tab. The odd thing is that no one ever gets the messages. The domain name is ourdomain.com in Mdaemon whch matches the actual domain name where our incoming mail is hosted at the ISP. I'm sure I have configured something wrong in MDaemon but am not sure what. I have tried changing the domain name to ourdomain.biz and changing the dns and nothing seems to fix the issue. Any help would be greatly appreciated.
