O Hotmail bloqueia meu servidor SMTP [duplicado]

Question

Recentemente, descobri que o hotmail bloqueou o SMTP novamente.

O código de erro é Diagnostic-Code: smtp;550 SC-001 (COL004-MC5F28)

Eu só envio para o meu jogo de texto on-line em 2D: link

• Emails de ativação
• Emails de recuperação de senha

É grátis jogar, então você pode se registrar para testar os atributos de e-mail. Depois de se registrar, você receberá um e-mail de verificação

Eu entrei em contato com a equipe da Microsoft e eles rapidamente removeram o bloco, felizmente. Mas eu quero evitar mais bloqueios

Aqui um código-fonte de e-mail é enviado do meu servidor SMTP para minha própria conta do hotmail

Então, há algo errado com a configuração do meu servidor? alguma coisa faltando? o que você sugere? obrigado

Answer 1

Você não deseja apenas verificar o e-mail que sabe enviar, mas procurar por e-mails que não esperava enviar, como scripts comprometidos ou contas de e-mail. E sim, os e-mails de verificação também podem ser marcados como spam. Você pode tentar um double opt-in, onde o primeiro e-mail enviado é pedir permissão para enviar outros e-mails, até mesmo e-mails de recuperação de senha. Então, tenha boas informações de desativação no próprio e-mail.

Dito isto, o seu IP parece estar limpo nas principais listas negras: link

O salto é apenas a Microsoft, e eles simplesmente não jogam bem com o resto de nós. Na minha experiência, nunca encontrei um único incidente de spam sendo enviado por qualquer IP que a Microsoft tenha bloqueado. Suas decisões parecem ser na maior parte arbitrárias, e tipicamente incluirão o bloqueio porque você tem um IP que se parece com um IP que eles bloquearam. Então, solicite um fechamento de lista e não se preocupe muito com isso. Se dependesse de mim, as pessoas parariam de usar esses serviços para o e-mail, mas, desde que estejam, provavelmente estão acostumadas a perder o e-mail de outras fontes legítimas também.

    

Answer 2

Dê uma olhada nestes dois cabeçalhos PCL entre 1-3 é bom. Mas SCL de 5 é considerado Spam

X-MS-Exchange-Organization-SCL: 5
X-MS-Exchange-Organization-PCL: 2

link link

Mas também noto o wl: 1 (acho que eles o listaram na lista branca), se esse for o caso, você pode não ter nada com o que se preocupar. Eu acho que o maior problema é que você está usando o GODADDY para enviar o email, acho que todo mundo que os usa tem algum tipo de problema de entrega, porque seus IPs são comumente usados de forma abusiva. Você pode enviar seu e-mail por meio de um Verificador de configuração de e-mail e ver o que acontece.
