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
