Outlook Rule Does not run automatically

[Jon]

Hi,

I have created a rule to automatically delete some spam emails.
Unfortunately it is the "MSN Featured Offers" type of email where it appears
to be coming from myself. Therefore I cannot delete on addressee. My rule is
constructed as follows:

"Apply this rule after the message arrives
with MSN Featured Offers in the body
permanently delete it
and stop processing more rules"

This is the last rule in my rule list. I've checked that none of the rules
preceding in the list have "stop processing more rules".

The rule should run automatically but it does not. It works fine when I run
it manually.

I'd be grateful for some help.

Thanks

Jon
