Email forwarding from Cloudfare

Hi. I contacted support and they are looking into it and also suggested me to post up here to see if anyone has information about this.

I added my email address for my account here to the email routing - Destination addresses section. Cloudfare sends a verification email so you can click it and your forwarded to email address gets added to your destinations. For some reason, those emails from Cloudfare don't make it to the inbox. I was asking support if there was something happening here where Mailbox is blocking Cloudflare's outbound IP range 104.30.0.0/19 or to try to add that to my whitelist but i don't see anyway to do that. My virus and spam settings are a relaxed as i can make them.

That's it. If anyone has any info on this or advise, i sure would appreciated it.

Thanks,
