Sendmail configuration and control

The below command's helps you after configuring the sendmail.

Examples	What it does
sendmail -bp or mailq	Displays the status of the mail queue. List Email files waiting to be sent and incoming.
ps ax | grep sendmail	Lists the process status of the sendmail daemon. May display something like....... sendmail: accepting connections on port 25
sendmail -bi or newaliases	Rebuilds the aliases database. Should be run after any changes are made to the alias file.

Run the below commands after configuring the sendmail

  cd /etc/mail 
  /usr/bin/make
  /usr/bin/newaliases
  /etc/init.d/sendmail restart
  /etc/init.d/spamassassin restart

The make command will create a new sendmail.cf file from the sendmail.mc file and compiles supporting configuration file in the /etc/mail directory according to the instructions in the file /etc/mail/Makefile.

The newaliases command generates new e-mail aliases, the newaliases and m4 commands require the sendmail-cf and m4 RPM packages. All theses packages must be installed. If they are not installed then, you'll get errors when running various sendmail related commands.

The sendmail command restarts the sendmail service.

The spamassassin restarts the spamassassin service, if it is installed.

Rebuild the new sendmail.cf file from the sendmail.mc using either the Makefile in the configuration directory or by issuing the command

  m4 sendmail.mc > /etc/sendmail.cf
               OR
  cd /etc/mail 
  /usr/bin/make

Find the status of mail sent in your server using grep command from the maillog

  /var/log/maillog | grep mail_id

Find the status of mail sent in your server using grep command if you are using exim mail server

  /var/log/exim_log | grep mail_id

Hope this will be handy for you folks :-)
