In theory, yes. In practice, it's likely much the same as many other
step-up protocols where, once a client tries to step up and fails, the
default behavior is to issue and error and give up.

In this case, that could be considered good or bad, depending on how
important the success of that encryption was to you (e.g. a transient
failure might expose mail that every other time it is sent is
encrypted).
