If I resend a message by Message -> Redirect the Date: header is updated on the message that is sent out. There is also Resent-Date: header that is correct (and other resent headers). The Date: header from the original mail should be preserved.
tags 360061 confirmed found 360061 2.6.0-2 stop I can confirm this bug for evolution 2.6.1. Most notably the date is changed, but also header order is changed. I can't see when header ordering should be a problem, but in either case we should aim to conform to RFC 2822 section 3.6.6.
