This proposal aims to fix that by specifying a way to add contact details +of admins, as well as a link to a support page for users who are having issues with the service. + +This proposal aims to fix https://github.com/matrix-org/matrix-doc/issues/484 + +## Proposal + +The proposal suggests adding a new endpoint: `https://{hostname}/.well-known/matrix/support`, +where `hostname` is the server name, without the port number. This is the same as what is used +when performing server discovery. + +The response format should be: + +```json5 +{ + "contacts": [ + { + "matrix_id": "@admin:domain.tld", + "email_address": "admin@domain.tld", + "role": "m.role.admin" + }, + { + "email_address": "security@domain.tld", + "role": "m.role.security" + } + ], + "support_page": "https://domain.tld/support.html" +} +``` + +The `contacts` array is optional, but recommended. + +The `matrix_id` and `email_address` do NOT need to have the same domain as the homeserver. It is expected that +an admin will have a "backup" contact address if the server is down, like an email or alternative mxid on a different homeserver. + +Entries may have a `matrix_id` OR an `email_address`, but at least one MUST be specified. + +`role` is an informal description of what the address(es) are used for. The only two specified in this +proposal are `m.role.admin` and `m.role.security`. + + - `m.role.admin` is a catch-all user for any queries. + - `m.role.security` is intended for sensitive requests + +Implementors may use custom values for role for other purposes, but it's suggested +that the value be namespaced to prevent collisions. A value for `role` MUST be specified. + +`support_page` is an optional property to specify a affiliated page of the homserver to give users help +specific to the homeserver, like extra login/registration steps. + +At least one valid key should be provided. This means `contacts` should have at least one entry, or the `support_page` should be defined. An empty object is not considered valid, however both `contacts `and `support_page` may be specified together. + +## Alternative solutions + +Hardcode a given user localpart that should be used as an admin address. + - The account would need to either internally redirect messages intended for @admin:domain.tld to another account(s) + - OR require an admin to regularly sign into this special account to check for messages. Neither of which is useful. + +Specify the same content inside a homeserver endpoint, rather than use `.well-known`. + - This requires the homeserver to be up or responsive, which might be not very useful if trying to report issues with + connectivity. + +Use vCards. + - vCards would add bloat, as the vast majority of a vcards contents is not useful for contacting an admin. + +## Security considerations + +If the host is compromised, any information could be specified in the well known file which may direct users to send +sensitive information to a malicious user.
