This is an attempt to post to my blog via email. If it works, then one postie cron job does the trick, otherwise I’ll have to set up a postie cron for each blog on the system… let’s find out!
Nope - to make postie work per wordpress install, you need a separate cron job to read each post. On the plus side, you can give each install a different periodicity and give infrequently updated instances a suitably infrequent check cycle.
