I have my own (personal) domain where all email sent to this domain is forwarded to my Gmail account. For this purpose I use the ZoneEdit MailForward function.
Since about 3 days (without changing any DNS records), my email does not arrive anymore on my gmail account. I have 1 other domains where emails are forwarded in a similar way (to the same gmail account), but they do still arrive.
What can be the reason that the email does not arrive anymore? The domain (website) is still active and has not yet expired. Is there some sort of mail policy introduced (like SPF?) that prevents mail forwarding?
