Can you be prosecuted for repeated unwanted emails to government offices or officials?

Can calling government offices or officials to insult them — especially after being told to stop — be punished the way that calling a private individual to insult them might be? I think the answer should be “no,” and the lower court precedents on the subject seem to agree; but in two recent cases, government officials seem to think that such speech can indeed be criminalized.
