Review on OnDMARC by Red Sift by Rey Hossain

The speed of implementation, easy configuration process.

It was really quick for us at work because we had some previous experience using this software but if you don't have any it can be very difficult especially when there are so many options in terms or configurations needed before getting things working correctly as well. We use our mail gateway provider which allows only certain domains/subdomains outbound emails from internal servers through their SMTP relay service however it seems like they block all other mails not coming form trusted sources such as gmail etc.. If those rules were more flexible regarding that I would say its great otherwise no real complaints just maybe make them configurable somehow! Email security is definitely improved since implementing these services into place.
