When you typed in sudo sendmailconfig  you should have been prompted to configure sendmail    For reference  the files that are updated during configuration are located at the following  in case you want to update them manually     etc mail sendmail conf  etc cron d sendmail  etc mail sendmail mc   You can test sendmail to see if it is properly configured and setup by typing the following into the command line     echo  My test email being sent from sendmail     usr sbin sendmail myemail domain com   The following will allow you to add smtp relay to sendmail    Change to your mail config directory  cd  etc mail   Make a auth subdirectory mkdir auth chmod 700 auth   Create a file with your auth information to the smtp server cd auth touch client-info   In the file  put the following  matching up to your smtp server  AuthInfo your isp net  U root   I user   P password    Generate the Authentication database  make both files readable only by root makemap hash client-info  lt  client-info chmod 600 client-info cd      Add the following lines to sendmail mc  but before the MAILERDEFINITIONS  Make sure you update your smtp server   define  SMART HOST   your isp net  dnl define  confAUTH MECHANISMS    EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN  dnl FEATURE  authinfo   hash -o  etc mail auth client-info db  dnl   Invoke creation sendmail cf  alternatively run make -C  etc mail    m4 sendmail mc  gt  sendmail cf   Restart the sendmail daemon   service sendmail restart

Combine two answers above  I finally make it work  Just be careful that the first single quote for each string is a backtick     in file sendmail mc     Change to your mail config directory  cd  etc mail   Make a auth subdirectory mkdir auth chmod 700 auth   maybe not  because I cannot apply cmd  cd auth  if I do so    Create a file with your auth information to the smtp server cd auth touch client-info   In the file  put the following  matching up to your smtp server  AuthInfo your isp net  U root   I user   P password    Generate the Authentication database  make both files readable only by root makemap hash client-info  lt  client-info chmod 600 client-info cd      Add the following lines to sendmail mc  Make sure you update your smtp server  The first single quote for each string should be changed to a backtick     like this  define  SMART HOST   your isp net  dnl define  confAUTH MECHANISMS    EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN  dnl FEATURE  authinfo   hash  etc mail auth client-info  dnl   run  sudo sendmailconfig
