    We just upgraded to 9.7.1. C2 and found that cpanel/exim adds a new header like this:

    Sender: <user@host.domain.com>

    This header is basically the username on the server and the host name of the server where the user is hosted.

    This creates big problems because now the messages appears to be from that address. This leads to the result that now Outlook will show the message to be from:

    user@host.domain.com on behalf of (the real sender)

    Customers will not like this because spam filters suddenly on the client side no longer work!

    ok, after further research it seems that the problem is the Sender: header. This header is normally only added if the server acts as a relay and a message is relayed to somewhere else. Incoming email to a local account is not relayed at all since the domain and user is local.

    Not only this, but on top when replying to an email the old email header will show the full username in Outlook as the recipient!

    This is so critical that we might want to go back to the last stable release!

    oh, thaphantom is responding, of course. sometimes I wonder if you get paid to defend cpanel or even work for them.

    Let me try to explain it so even you understand. A Sender header is only injected in systems for relayed! mail. An email that is sent from host A (for example Yahoo or Hotmail) to host B (the cpanel/exim host) and will not leave host B is not considered relayed!
    This means injecting a sender header is incorrect. Otherwise you would have to inject one for every outgoing message as well. Sender headers should be human administrated addresses according to rfc. The username of a host in a cpanel environment is hardly used or checked as we all know. This is why the envelope from address is used.

    In any case, injecting a sender header for incoming email that is for a local account is simply incorrect.
