There is a section on conditionals, including examples, in the documentation.

You cannot place a conditional inside a filter (or input or output). So you need to reverse the order of those two lines, add a { at the end of the if, and add a } before output {.

Once you get that fixed you will have a problem with the grok, probably a timeout. As a rule of thumb, you should only have one DATA or GREEDYDATA in a pattern. 91 is not going to work. Are the emails really all in a very specific 92 line pattern?
