Email Validation: Outbound

Siebel by default does validation of the email addresses that are being used in the 'Outbound Communication Manager'. Basic validations like having a '.com' or '@' are present. Some times there might be a busniess requirement where these validations needs to be overwritten to cater to the customer needs where they might encounter validation errors.
To implement this requirement we need to set below system preferences:

A> Navigate to Administration – Application  –> System Preferences

B> Query out 'Enable EmailAddress Validation' and set its value to 'FALSE'

C> Perform Siebel Service restart.
