A temporary inbox service. Visitors pick an address at one of its domains, use it for a signup or a download, and the inbox is discarded shortly after. No account is needed, so one person can create as many addresses as they like.
mail-mx.org rotates domains so that blocked ones are replaced. Most new disposable domains are on no public list when UserCheck first sees them, which is where a static blocklist starts to leak. Checking the address at signup picks them up as they appear.
Use an API like UserCheck, which keeps track of temporary email domains for you. Send it each address when someone signs up and reject the ones that come back with disposable: true. The same check covers mail-mx.org and every other temporary email provider UserCheck tracks.
New domains are picked up as they appear, so there is no list to download or keep current.
