======================================================
if you did not received any mail in your inbox then do the following.,
I’ve used this method with small adjustment, and it works perfectly.
As we already Installed mailutils ,When the setup wizard launches, choose the unconfigured option. You don’t need to do any special configuration to get this to work.
next Install and configure sstmp as follow:
~ sudo apt-get install ssmtp.
then enter into the directories of etc,ssmtp,and edit the file ssmpt.conf using vi or vim or nano i have done as follow.,
~ sudo /etc/ssmtp
i entered into ssmtp directory now ,i open the file ssmtp.conf using nano.
nano ssmtp.conf
then you enter into the file for doing the required adjustments as below
Uncomment FromLineOverride=YES by deleting the #
Add the following to the file:
AuthUser=<user>@gmail.com #add ad-min mail-id
AuthPass=Your-Gmail-Password #password of the ad-min
mailhub=smtp.gmail.com:587 #don't change it
UseSTARTTLS=YES
Save and close the file:
ctrl-x
Press Enter
screen cast:
If you’re using two-factor authentication do the follow:
Create a new application-specific password to use in the config file above. (If you’re using Gmail, you can manage those passwords here.)
After doing all required adjustments run the scribble,and check your mail or ad-min mail inbox.
screen-cast shows the successful sending of mail alert with out any error!!!!
