Sorry, it was my fault (accidentally)
But I fixed it in less than a minute. There shouldn't be any lost mail because senders must retry for around two days normally.
I have checked it now. There shouldn't be any problems. It is registered in Namecheap and points to asmallorange DNS, and that points the MX records to gourmet.spamgourmet.com. I guess the problem you are having is general or related to your account.
