[Zope] posting to a coreblog via email

I set up coreblog and it's fine. I can post to this the regular way etc. I've also set up an email address to which I can successfully sent email (and checked that this works via webmail) I've set up the blog settings to reflect the mail server, username and password for the POP account, password for adding entries and sender address. I send mail and then hit the URL at the bottom of the (moblog settings) page manually to test this. Nothing *appears* to happen and the blog isn't updated. Now I haven't set up the wget yet to hit that url. Do I need to before this will work or should it be working now ? Any ideas on where I can look for more help? Kate
