Wordpress emails not being sent (or received?)

I just noticed that my Wordpress emails aren’t being sent (or received; I’m not sure which). Comment notifications, moderations, etc., are set up to be sent, but I never get them at the address specified in my control panel.

Does anyone know of a limitation or setting on Dreamhost that might prevent them from coming through?

Other than the 100/hr quota, nothing should be stopping them. Mine have been working.

Thanks Scott. I guess I’ll have to disable the plugins, one by one, to see if that’s causing it! Glad to hear yours are working; at least that gives me something to start with.
