If sendmail-cf not install

Code: Select all: yum install sendmail-cf

# With the newly edited "sendmail.mc" file use make which will call the m4 (the sendmail macro burner) to create "sendmail.cf".

Code: Select all: cd /etc/mail make

The make will call the m4 macro burner

Code: Select all: m4 sendmail.mc > sendmail.cf

This site http://networking.ringofsaturn.com/Unix/sendmailtips.php
has some helpful info as stated

This is a quick document on how to get yourself out of some binds I've run into with sendmail. These aren't going to be the most organized, but I figure someone else may find these useful.

When I send emails they end up in /var/spool/mqueue but are not delivered.

When I type mailq on the server terminal
it lists the mails as being deferred
eg

(host map: lookup (mydomain.com.au) : deferred)

my solution was to check the /etc/resolv.conf file
and make sure the first name server listed was the ip address of my mail server which is also my dns server.

nameserver 10.10.10.183

If you have some specific jobs you'd
like to process in the queue, you can skip the rest of the queue processing and handle just those.

sendmail -v -qI {queue id substring}

or

sendmail -v -qS {sender address substring}

or

sendmail -v -qR {recipient address substring}

These variations will limit the processing to a sender address,
recipient, etc, in the queue.

When I try to send mail to a user on my local linux server called mydomain.com.au ,
an error is displayed in root's email

553: Sorry, that domain isn't in my list of allowed rcpthosts; 5.7.1

solution
edit sendmail.mc
add line

Code: Select all: MASQUERADE_AS(`mydomain.com.au')

save
then type

Code: Select all: make

then restart sendmail

Code: Select all: service sendmail restart

if sendmail-mc is not installed type

Code: Select all: yum install sendmail-mc

prior to make

I get an error that relay access is denied, the system is not configured to relay mail, or that the domain isn't in the list of allowed rcpthosts. Why?
