I'm trying to configure the sendmail on my ubuntu, the following should install the necessary packages:

sudo apt-get install sendmail sendmail-cf m4

But then when I'm changing the sendmail.mc file how I should compile it to see the changes in sendmail.cf file ??

This tutorial suggests the make command :

cd /etc/mail
make

but then the changes are not reflect in my sendmail.cf command. Also some suggests that :

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

But then I'm getting the error :

m4:/etc/mail/sendmail.mc:10: cannot open `/usr/share/sendmail-cf/m4/cf.m4': No such file or directory

So I don't know how to compile the sendmail.mc file !! And as I mentioned I have installed the sendmail, sendmail-cf and m4 packages.

I have given up on sendmail and discovered that msmtp is much easier to install. My old server was evidently linking sendmail to msmtp. sudo apt install msmtp I put settings in /etc/msmtprc:

defaults

timeout 15
tls on
tls_starttls on
tls_certcheck on
tls_trust_file /etc/ssl/certs/ca-certificates.crt


account default


host EMAIL_SMTP_SERVER
port 587
auto_from off
from ACCOUNT@DOMAIN


auth on
user ACCOUNT@DOMAIN
password PASSWORD

Test it:

sudo ln -s /usr/bin/msmtp /usr/bin/sendmail
echo "Subject: Sendmail (MSMTP) Test" | sendmail -v recipient@domain.com
