Some email that was sent to me via a burnermail.io account never reached me. The sender got no bounce, so the message just went into a silent black hole. Of course whenever this happens there is no way to know whether the msgs were lost by the forwarding service or the email hosting provider. Hence why I am asking.. would like to see if there is a pattern.

Worth noting that spamgourmet.com is very unreliable. Messages get dropped silently all the time. But until recently I was unaware of any possible issues with burnermail.
