No Emails coming in for admin or customers

[Noneya99]

One of the carts I've set up is not recv'g emails at all no order confirmation, account creation, extra CC orders, contact form, etc.. Nor does the customer recv' emails for account creations, order confirmation I've run numerous tests set up accounts using various emails .. have changed the email addys in the admin of where things get sent and nothing .. things worked fine prior to this .. orders show up (except all credit cards are missing middle digits b/c the extra cc info is not being email either) no server changes have been made recently and this apparently has been going on for at least a week and we just realized it after we logged in and saw there were orders waiting and yet we never got emails on any of it .. my carts on other domains are seemingly working fine (we have gotten emails from those) .. they are all on the same server but different IPs .. all mail servers are pinging and tracing just fine.. I've searched all over the boards and can't find anything other then where others are having the same problems but i've yet to see a response to any of them that seemed to help.

any and ALL suggestions are appreciated.
