Relaying denied, Sendmail 8.12.9
We have Linux 7.2 an sendmail 8.11.3. All users were able to send to internal und to external recipients if there IP-Adreess is known by our DNS.
Now I have cloned the disk and on the clone I installed sendmail 8.12.9. I am using the same sendmail.cf like I used with sendmail 8.11.3. Now no user is able send to an external recipient (all others intern -> intern, extern -> intern is possible). In /var/log/messages I read "Relaying denied". What is the mistake?
