[chibenwa]

Description

As a french user I want the relies I send to be localized in french.

Expected result

Current behavior

Additional information

The server supports i18n.

Supported locales for deployments are advertised in the session:

        "com:linagora:params:calendar:event": {
            "replySupportedLanguage": [
                "en",
                "fr"
            ]
        },

From there client can set the local it wishes:

{
  "using":["urn:ietf:params:jmap:core","com:linagora:params:calendar:event"],
   "methodCalls":[[ "CalendarEvent/accept",
     {
        "accountId":"50fb9073ba109901291988b0d78e8a602a6fcd96fbde033eb46ca308779f8fac",
        "blobIds":["123ddb30-1134-11ef-9d4e-7d1058f3d6e1_15"],
        "language:: "fr"
     },"c0"]]
}

And the backend would take care of the rest!

Today the language option is not specified by tmail...
