Not being able to receive emails from major business partner
It's been almost two weeks we can no longer receive emails from one of our major business partners. There is already a ticket in place but I am getting no feedback and no update status, every time I get a reply I have to explain everything all over again. The ticket number is 99908714.
This is the message that the sender gets when they send us an email:

You are basically blocking fortimail cloud mail solution from reaching us.
I already white listed the domain of our business partner, I already whitelisted some emails that normally reach us, I already white listed at least one IP but being a hosted mail solution they probably have more than one email and fortimail won't tell me all their IP addresses for obvious reasons.
Our business partner is currently BCC forwarding all the emails in his organization to a Gmail account and that's how we are able to function but it's completely unacceptable and it's already been two weeks.
Let us know if we need to find another mail provider.
