== !ServerAdmin Directive
Email address that the server includes in error messages sent to the client.

The `ServerAdmin` sets the contact address that the server includes in any error messages it returns to the client. 
If the server doesn't recognize the supplied argument as an URL, it assumes, that it's an email-address and prepends it with mailto: in hyperlink targets. 
However, it's recommended to actually use an email address, since there are a lot of CGI scripts that make that assumption. 
If you want to use an URL, it should point to another server under your control. 
Otherwise users may not be able to contact you in case of errors.

It may be worth setting up a dedicated address for this, e.g.

{{{
ServerAdmin admin@example.net
}}}

as users do not always mention that they are talking about the server!
