Eu recebo o email tranquilamente, mas pra enviar eu não consigo, pelo oque entendi é algo com bloqueio, mas como resolver isso?

Olá, tudo bem ?

Tive um problema com o seu!

Primeiro verifique se o seu servidor de e-mail tem uma boa reputação no seguinte endereço: https://www.senderscore.org/get-your-score/

Em seguida, você pode solicitar que o Hotmail remova seu endereço ip do banco de dados de bloqueio.

Para solicitar o desbloqueio de servidores para Hotmail, visite https://support.microsoft.com/en-us/supportrequestform/8ad563e3-288e-2a61-8122-3ba03d6b8d75 e informe os dados solicitados.
