Is MTA-STS worth setting up?

Has anyone setup MTA-STS? Would you recommend it?

Looks to me like there are some DNS settings to add (easy enough) and then a text file to host on a public facing server which seems a pain if you live in Workspace and don’t have public facing servers - is that about right?

Does it cause any issues with domains that don’t use/support MTA-STS or does it just fail over to standatd SMTP?

Thanks for your thoughts and inputs

You can host the policy file on a Google Cloud Bucket to ensure it’s been setup and easy to maintain.  Also practically free. 

Here is the “how to host” article (not mentioning the bucket but the subdomain)
