Right I've done the following:-
Sevice sendmail stop
Edited vi /etc/mail/sendmail.mc
Removed dnl from infront of smart host and put in the host name of the mail server which I can ping and it resolves to an ip.
Closed and saved
installed sendmail-cf via yum
make -C /etc/mail
to generate a new
Checked to see if the mail server is in there
# "Smart" relay host (may be null)
which it is
I still get errors when sending
(reason: 550-Verification failed for <email@example.com>) which is name of the server......
I'd like to change it so that appears to come from firstname.lastname@example.org
I Take it I use the masquarade function... any pointers
Sorry sendmail newbie
