It's been done in the past, but current practice is strongly against
it.  For example, in your own message that I'm replying to, there's
a DKIM signature (RFC 6376):

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=ewie.name; s=MBO0001;
	t=1728654419;
	h=from:from:reply-to:subject:subject:date:date:message-id:message-id:
	 to:to:cc:cc:mime-version:mime-version:content-type:content-type:
	 in-reply-to:in-reply-to:references:references;

	RDZ4MAxEzZKfOr8HGnubQf8FdQPGw6jlAn3U8199c+3QcIAWJ99Wrtb5rQPdEw==

That lists "reply-to" as one of the signed header fields.  So if the
mailing list were to modify Reply-To (including inserting one where
there was none before) a DKIM-verifying recipient would regard the
message as a forgery.
