voc\u00ea est\u00e1 sem tempo, aqui est\u00e1 a vers\u00e3o resumida de cada protocolo. O restante do artigo explica o motivo.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>POP3:<\/strong> baixa os e-mails para um dispositivo e pode remov\u00ea-los do servidor. \u00c9 mais indicado se voc\u00ea l\u00ea e-mails em um \u00fanico computador e prefere manter as mensagens dispon\u00edveis offline.<\/li>\n\n\n\n<li><strong>IMAP:<\/strong> mant\u00e9m os e-mails no servidor e espelha as mesmas pastas em todos os dispositivos. \u00c9 mais indicado se voc\u00ea acessa seus e-mails pelo celular, tablet e computador e quer manter tudo sincronizado.<\/li>\n\n\n\n<li><strong>Exchange ActiveSync (EAS):<\/strong> sincroniza e-mails, contatos e calend\u00e1rios em dispositivos m\u00f3veis. \u00c9 mais indicado se voc\u00ea quer ter tudo em um s\u00f3 lugar e prefere n\u00e3o precisar configurar o envio separadamente.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-post-office-protocol-pop3\" class=\"wp-block-heading\">Post Office Protocol (POP3)<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No POP3, o servidor de e-mail recebe todas as mensagens enviadas e as armazena na sua caixa de entrada.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O POP3 oferece uma maneira simples de baixar seus e-mails da caixa de entrada remota para a caixa de entrada local. Isso acontece porque o POP3 baixa apenas o conte\u00fado da caixa de entrada, e n\u00e3o o conte\u00fado das outras pastas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para fazer isso, o protocolo POP3 se conecta ao servidor, rastreia todas as mensagens rec\u00e9m-recebidas (apenas na caixa de entrada) e as transfere para o cliente de email instalado no computador do usu\u00e1rio. Dependendo das configura\u00e7\u00f5es definidas pelo usu\u00e1rio, os e-mails originais podem ser mantidos ou exclu\u00eddos do servidor ap\u00f3s serem baixados para a caixa de entrada local<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Observa\u00e7\u00e3o:<\/strong> O processo de envio de emails \u00e9 bem diferente do processo de recebimento. Ao enviar um email a partir do seu computador, por exemplo, a mensagem fica armazenada localmente. Ou seja, ela n\u00e3o pode ser encontrada na caixa de sa\u00edda do servidor em outros dispositivos.<\/p>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter wp-image-2800 size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"483\" height=\"120\" src=\"https:\/\/blog.mailfence.com\/wp-content\/uploads\/2017\/09\/Mailfence_POP3.jpg\" alt=\"Mailfence POP3\" class=\"wp-image-2800\" title=\"Mailfence POP3\" srcset=\"https:\/\/blog.mailfence.com\/wp-content\/uploads\/2017\/09\/Mailfence_POP3.jpg 483w, https:\/\/blog.mailfence.com\/wp-content\/uploads\/2017\/09\/Mailfence_POP3-300x75.jpg 300w, https:\/\/blog.mailfence.com\/wp-content\/uploads\/2017\/09\/Mailfence_POP3-160x40.jpg 160w, https:\/\/blog.mailfence.com\/wp-content\/uploads\/2017\/09\/Mailfence_POP3-320x80.jpg 320w\" sizes=\"auto, (max-width: 483px) 100vw, 483px\" \/><figcaption class=\"wp-element-caption\">Post Office Protocol (POP3) &#8211; Mailfence<\/figcaption><\/figure>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 id=\"h-pros\" class=\"wp-block-heading\"><span style=\"text-decoration: underline;\">Pr\u00f3s:<\/span><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>O POP3 \u00e9 mais \u00fatil se voc\u00ea acessa seus e-mails por apenas um dispositivo.<\/li>\n\n\n\n<li>Voc\u00ea pode ler e organizar seus e-mails offline, com mais praticidade.<\/li>\n\n\n\n<li>O protocolo \u00e9 uma op\u00e7\u00e3o para quem prefere armazenar os e-mails nos dispositivos locais em vez de mant\u00ea-los em um servidor remoto por quest\u00f5es de privacidade.<\/li>\n<\/ul>\n\n\n\n<h4 id=\"h-contras\" class=\"wp-block-heading\"><span style=\"text-decoration: underline;\">Contras:<\/span><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sem sincroniza\u00e7\u00e3o entre dispositivos.<\/strong> Se v\u00e1rios dispositivos acessarem a mesma caixa de e-mail via POP3 sem excluir as mensagens, cada dispositivo ficar\u00e1 com sua pr\u00f3pria c\u00f3pia separada.<\/li>\n\n\n\n<li><strong>As a\u00e7\u00f5es n\u00e3o s\u00e3o sincronizadas.<\/strong> Tudo o que voc\u00ea fizer com uma mensagem, como exclu\u00ed-la, mov\u00ea-la para uma pasta ou adicionar uma etiqueta, ser\u00e1 aplicado apenas no dispositivo em que a a\u00e7\u00e3o foi realizada.
