Reply-To address change automatically

[Original post]
I am getting emails from sender@a.com domain. A transport rule is applied this mails to redirect to external address Sender@c.com and and a copy to my mailbox sender@b.com.

When then mails received at external address mailbox , In the message header shows Mail from: Sender@a.com and the reply-To address shows sender@b.com

Is any way we can change the Reply-To address to Sender@a.com?

Hi,
Did the sender set the Reply-To address to sender@b.com when sending the message?

And to my knowledge,the Reply-To address cannot be modified via transport rules.
