Does anyone know if ipowerweb limit the number of email you can send out (eg 100 per hour? 500 per hour?) If so what is it? I run a community newsletter with nearly 1200 subscribers and my first attempt at sending it out had at least half bounce back from ipowerweb with an "unrouteable mail domain" error (the domains were not the problem).
I am guessing that this is probably due to sending too many at one time, hence my question.
