Can Support or anybody else advise on how to block disposable /temporary email services?
Is that part of the build-in solution?
Thank you for contacting the Sophos Community.
If you meant to say the Domains that are like "10 minutes mail" you could use the Global Allow/Block to block these domains.
Currently Central Email, doesn't have an option to detect temporary/disposable emails and block them. That would be a feature request that you can add in the following link: https://ideas.sophos.com/forums/428821-sophos-central
Maybe something like https://spameatingmonkey.com/services/SEM-FRESH30 for domain names?
