Is this possible within SaaS to block email based on the originating geolocation. We would love to be able to blocked emails originating from certain countries. We have already done this with our firewall and it has helped tremendously.
You can block mail based on the domain extension, such as .ru, .cn, etc. but we do not scan mail to determine where it originated.
I hope this information helps!
