Disable all outgoing e-mails


Well-known member
I know in vBulletin you can add a line to the config.php file to disable all outgoing e-mails and communication. This is handy when copying an active forum/database to a test environment from which you do not want any e-mails (i.e. notifications, conversation notices, etc.) sent out.

Is there a similar way of achieving essentially the same thing with XenForo?

Can't you just remove the email address from within the ACP?

I just tried it and didn't get an error but I don't know how it will work in practice.

No I mean the main email address from which all emails are sent.

Options -> Email Options -> Default Email Address
I wouldn't think that that would disable the sending of e-mails. I assume it would just send them without a return address. But I'm not sure.

Thanks for this - exactly what I was looking for. Is there any documentation which outlines all available $config directives?
