Our mail accounts are hosted outside our intranet with a web hosting company, which is also holding our DNS record.
Is it possible that all the problems with sendmail are actually DNS problems and how can I test this?

Appreciate you help !

You can test if this are DNS or routing problems:

Please try to connect to the yahoo mailserver via telnet on the shell of your server. Enter the command:

telnet 25
When you got an answer from the serve, you can close the connection by typing "quit".

The testsession should look similar like this:

# telnet 25
Connected to
Escape character is '^]'.
220 ESMTP YSmtp service ready
Connection closed by foreign host.
If not, please post the output in the forum.
