I am still confused regarding this. please help .Thanks in Advance
${...} are resolved by the properties placeholder from mail-configuration.properties.
That is entirely different to SpEL which evaluates expressions (usually not just simple properties) during context initialization.
For example #{someBean.foo} will get the value by calling getFoo() on someBean, and
#{SystemProperties['bar']} will use the value from the bar system property
(java ... -Dbar=baz).
