That's not good.
Is there a way in your email application to view the entire original email without any formatting? Then we could see if the "Reply To" header actually made it. I'd look for something that looks like this:
... To: [email protected] Subject: =?UTF-8?Q?testing... testing?= Reply-To: Name <[email protected]> MIME-Version: 1.0 Content-type: text/html; charset=UTF-8 ...
Hmm, that is an interesting idea. I've always just assumed the standard email format was what users wanted and changing the way gpEasy sends an email would be like trying to invent the wheel. For example, when an email is sent from thunderbird to outlook, it doesn't add "New message from", "Subject" etc to the message. Those are all already parts of the email. But maybe it could be different. Personally, I've been happy with the way it works and it sounds more like a problem with Outlook or Outlook settings, but does anyone else have strong feelings?
