How to prevent 'reply-to' header in outgoing mails?

Hi, how can I stop eM Client from adding a ‘reply-to’ header to every outgoing mail?

Unfortunately you can’t.

It is a standard function of email messages.

Yeah, it’s a standard function of email messages, but it’s optional. Actually, a ‘reply-to’ header which is identical to the ‘from’ header doesn’t bring any added value, but only confuses the recipient. Outlook and Apple Mail don’t add this unnecessary ‘reply-to’ header. It would be great if eM Client wouldn’t do it either.
