Overriding Email Sender User Name Dynamically

Can define multiple sender name in Send Email action like recipient email?.

Currently I have defined the default username in ServiceCenter but I want the sender to be dynamic. I tried providing the sender email in Send Email "From" field, off-course it's throwing error  "Authentication Required".

Is it possible to dynamically change the sender email without credentials?.

Hi Karnan,

The "From" field is exactly meant to be used for the purpose you want to use it. The error you get makes me believe that your SMTP server only allows e-mails to be sent if they are coming from a specific e-mail address. This is not Platform-related, and should be solved by whoever is responsible for that.
