You submit a message and you're done a second later. Worst case the server waits longer and you're tying up a thread (if you're not using Async) or a completion port. Hardly a problem. Error handling exists to deal with this both for connection failures and timeouts. Crying for a service to handle this is like a using a jackhammer to dig up a flower.

Sorry for asking too many questions. When you are saying "call it directly" you mean call a class/method of the ASP.NET application that sends emails?
