Is MailKit thread safe?

Well, no. Unlike HttpClient, the Send/SendAsync methods are not thread thread-safe. So unless you want to introduce your own synchronization scheme, you can’t use it that way either. So for the time being they are simulating async support by simply calling the synchronous code paths and blocking threads.
