Unable to send emails to my own domain
i have a fresh install of Redhat 9.0 and have not changed any of the sendmail configuration options (yet). I have also installed Bugzilla on this machine and need the ability to send email notifications to people when there are bug updates. I really dont understand sendmail very well because ive been very successful at dodging it, at the same time, i am a bit of a veteran at Linux admin stuff. Anyway, i can send emails to any other domain except for my own. For example, i can send an email to email@example.com but i cannot send an email to firstname.lastname@example.org. If i sent it to mydomain.com then the message is returned as 'Returned mail'. I get the following message within that mail stating: Host unknown (Name server: 192.168.20.101.mydomain.com.: host not found). Now, the confusing thing is that 192.168.20.101 is the ip address to my mail.mydomain.com (which is where i want the email to be relayed to) but it seems to take the ip address and append on the domain name again. Here is the lowdown on my versions:
Red Hat Linux release 9 (Shrike)
Any help would be greatly appreciated...
