I posted originally here but got no reply
Seems I am having the same problem with automessage.
I have set it to send a immediate message on creation of new blog.
as a test i created a new blog, as a user word not from admin.
got the activation email
got the new site email
got the anti-splog email
unspam / ignored it
admin account got new blog registration email
main screen shows 0 queued.
and thats it attached is the automessage screenshot
