Sender vs From field in MailMessage Class

Please go through this link.
what is the difference between sender and properties of mailmessage class. How can we use both of these properties. Aren’t they same ?

@alishasharma,

Thanks for contacting us. I like to inform that from is the email address of the author(s)
while sender is address of the actual sender acting on behalf of the author listed in the From: field (secretary, list manager, etc.).

@Adnan.Ahmad,
Thank you. This means I should use information from From field to insert info in EmailOnBehalfOf and from “Sender” field to insert info in EmailFrom section ? Am I right ?

@alishasharma,

Yes, you are right.
