I have a server-config Mac mini set up at home. When I had Snow Leopard on it, I had started setting up a mail server, but left it in a half-configured state of some kind. I've since upgraded to Lion. The mail server seems to be working fine; that is, I can send and receive mail, but my admin account is getting a copy of every message received by the mail server. I do remember checking a box in Snow Leopard server admin that seemed to be intended to set up this behaviour. Now that the server is running though, I'd like to disable it. How can I turn off this behaviour in Lion Server? The check box to handle it isn't in the Lion server admin app.

I'll give you two choices:

First, you can edit the file /etc/postfix/, and delete the line that starts "always_bcc=". You'll need root access to edit it; if you're comfortable using a command-line editor like vi or nano, you can just use that with sudo. If you're not comfortable with that, I recommend using TextWrangler -- it can use your admin credentials to edit root-only files in the GUI.

Second, you can install the Server Admin Tools (10.7.2 version is here). It includes Server Admin, which includes advanced mail server settings, like enabling/disabling the always_bcc option.

Gotem. Thanks. I was actually snooping in when this answer showed up. I'll go check out Server Admin Tools. – Carl Norum Oct 14 '11 at 4:51
