Email suddenly stopped working

[meljen]

My domain and attached email for my shop is Godaddy. I use liquid web for hosting. I have had my email set up with my domain email ([email protected]) for just over a year now, with almost no hitches at all, except that this happened once before. I heard that godaddy has hidden limits on emails and some seem to get lost for no reason, which is really REALLY frustrating.

I use an email puller for my various email accounts (thunderbird email client). It's never had problems, except when I change my email passwords, which I didn't, and I would have received an error. I double-checked by directly logging into my godaddy email from their website. Oddly enough, a couple emails have come through over the past few days, but none from my shop. However, I am receiving Paypal notices of customer orders... just no invoices or anything else.

I am really worried about what might be going on. I thought of calling godaddy, but I have friends who were given the run-around regarding email troubles. So I figured I would check here first. Here are my email settings in my zen cart. Like I said before, this has been working fine for just over a year, and I have not touched any settings since I first set up my shop.

As you can see (even though it's being hidden with hash tags in this post), I use a gmail address for email copies so I can see invoices and whatnot coming through, to HOPEFULLY help prevent the hidden email limit that godaddy has. Previously I had all emails set to [email protected] and there were just too many emails sent, I guess.

I'm not even getting invoice copies. Nothing is being sent to me at all, except notices from Paypal when I'm paid.

Any help would be appreciated.

*edit* It's important to note that I cannot move email/domain providers right now, though I hope to soon as I am very tired of godaddy. I simply need help to make sure my emails can get through until the move can be done.
