How to fix "403 Throttled" errors for trackback pings in Movable Type

For a while now, I've been having problems with getting trackbacks sent out of this blog. (Mostly to Wordpress blogs using Akismet I've noticed but that's besides the point.) 

I did note a number of times I received a "403 Throttled" error within my activity logs.  A quick google search pulls up this article on Richard Green's site on How to fix "403 Throttled" errors for trackback pings in movable type.

Richard tells us to add in the settings OneHourMaxPings and OneDayMaxPings to your site's /mt/mt-config.cgi file. (I note that as SixApart's docs don't actually say where to put those settings.) I've gone ahead and placed both lines in my config settings and saved the files.

...And watched the number of spam trackbacks go skyhigh.

Oh well.  At least my trackbacks are going out now.
