MWEB IGNORING ISSUE OF EMAIL'S BEING RETURNED. Happening for years.

Emails are being returned. For YEARS I have been complaining that I don't receive certain emails. I was just informed that more emails were returned. PATHETIC CUSTOMER SERVICE since Internet-solutions took over. Clients may not be aware that important emails are not being delivered.

THEY NO LONGER SEND A WARNING THAT AN EMAIL WAS REJECTED. WHY?
