$MessageList

$MessageList
is a global variable that gives a list of the names of messages generated during the evaluation of the current input line.

Whenever a message is output, its name, wrapped with HoldForm, is appended to $MessageList.

With the standard Mathematica main loop, $MessageList is reset to when the processing of a particular input line is complete.
