Hey, hi!

I see you're having troubles with spam, it happens. I'm receiving this message when a mail is sent from my Zoho to my Gmail (x-out stuff to protect me, added info in red):

The following message could not be forwarded to xxx@gmail.com (my gmail) for xxx@xxx.com.br (my zoho)

Should I worry or do anything to get the forwarding to work? I received about 8 of these messages and I'm afraid I'll lose any important email.

Thank you very much, have an awesome day!
