Eu estava vasculhando minha pasta de spam (o que raramente faço, porque o Gmail raramente tem falsos positivos) e notei algo interessante:
Algo como mais da metade das mensagens tem pelo menos um emoji animado no assunto.
Nenhum dos meus amigos usaria essa porcaria. Nenhuma empresa válida com a qual eu faria negócios jamais faria isso também.
Como posso criar um filtro para, talvez, excluir automaticamente mensagens com emoticons animados no assunto?
Usando a pista de jamesmstone abaixo, tentei pesquisar com subject:=?UTF-8?
e subject:"=?UTF-8?"
e várias outras permutações, mas nenhuma funcionou.
Aqui está um exemplo de conjunto de cabeçalhos de uma dessas pilhas fumegantes:
