Folks may've seen SMTP debug errors and the like over the last little while - there was (maybe still is?) a problem with email notifications tied to events like PM's and subscribed threads, the problem is/was server-side (beyond our control).
When this happens, It doesn't mean your post isn't going thru, it just means that people who would receive email headsup of your post, wont get that email. The same symptoms would pop up from time to time if the ISP handling outbound mail for Toyspeed has a glitch.
FYI.
