Systems, methods, apparatuses, and software for electronic mail systems and service in computing environments are provided herein. In one example, an email service is provided that receives receive requests for endpoint information that correspond to email identities included in the requests. For ones of the requests that indicate invalid email identities, the email service determines responses that conceal validity of the invalid email identities by deriving target endpoint information based at least on the invalid email identities, and provides the responses that indicate the target endpoint information.

Email address farming mitigation

An asynchronous engine identifies API calls that are to be made in order to fulfill a received service request. The asynchronous engine secures a separate computing thread for making each API call, and generates the API calls on the separate computing threads. Workflows performed in responding to the service call interact with the asynchronous engine to obtain results from the API calls.
