Not sure if anyone else has figured this out yet....

At the bottom, where it has the quick reply, which I think most people use, it has the subject line. When the subject line has too many 's because of so many replies, and it maxes out the number of space.... ding ding ding, you get postpro problem.

So, if you get postpro error, go back, re write it out, and DELETE the subject line of your reply, at least all the 's
