Yes, they all seem to be alright.
Next, let's try to telnet to the smtp port:
- from the localhost. Simply telnet localhost 25 and try to submit a
sample msg.
- from any other machine that is in the same subnet as the mail server
>From any other remote hosts we already know that it fails. But do you
refer to the MTA by address or by name? Check the DNS entries for the MTA:
host -t mx yourDomainName
host -t a theResultNameFromPreviousCmd
Is it the same IP as assigned to the server?
