Seeking Alpha indicates email is not working

I keep getting messages from SA that I am not receiving emails.  My email works perfectly.  Please turn off this odd feature, there has to be some type of bug in your server that wants only gmail, outlook or icloud email addresses.  This is getting annoying and there is no obvious way to fix the problem.  I keep testing my email and it keeps working.  I keep clicking the button to turn my email back "On" and, initially, I always receive emails.  Nothing from SA is going to my spam, it works perfectly!  The issue is on the SA side.
