Forwarding catch-all mail to gmail fails.

Forwarding catch-all mail to gmail fails.

Hi,
I have a catch all email address on didi.org.il which forwards (or supposed to) all emails to a gmail account.
it seems that the forwarding isn't working properly, i see the email in the zoho mail box, but nothing on my gmail account (i sent to catch@didi.org.il).

how do you troubleshoot this issue?

Thanks.
