on [<modes>]server_notice [<serial#>] [-|^]<match> { <action> }

This event is thrown when the server you are connected to sends you a notice and you didn't handle it in a more specific way. If a remote server sends you a NOTICE it will be treated like a notice from another irc user and routed through on general_notice.

There are several different type of server notices, and they are processed differently by the client.

A kill notice starts with “* Notice – Received KILL message for” and that will throw an on kill event, If you don't catch that, it will treat it as an oper notice. An oper notice starts with “* Notice –” and that will throw an on oper_notice event, and if you don't catch that, it will treat it as a general notice.

A server notice will throw an on general_notice event. If you don't catch it, it will throw an on server_notice event. If you don't catch that, it will format the message and display it to your SNOTE window.
