+    PWDEMAIL="plalala"  ## ATTENTION DONT USE Special Chars.. like as SPACE # and some others not all. Feel free to test ;)
+    MAILPROV="smtp.google.com:583"
+    DOMPROV="gmail.com"
+    USERLOC="root"
+    #######
+    apt install -y ssmtp
+    cp -r --preserve /etc/ssmtp /etc/ssmtp.bck
+    echo "AuthUser=$MYEMAIL
+    AuthPass=$PWDEMAIL
+    root=$MYEMAIL
+    mailhub=$MAILPROV
+    hostname=$HOSTNAME
+    FromLineOverride=YES
+    UseTLS=Yes
