Cache Size warning..How to turn off email reminder?

AO does not automatically clear the cache saudpds, lots of info on the what and why (and even links to 3rd party solutoins) in the Autoptimize FAQ.

The email-warning can be turned off with the following code snippet;

add_filter('autoptimize_filter_cachecheck_sendmail','__return_false');

hope this helps,
frank
