Eu olhei para algumas das perguntas / respostas do SF existentes e até agora não consigo encontrar a mesma situação. Não é um problema de TLS como eu pensei, já que o servidor remoto não está pedindo TLS, e não é um problema de firewall desde que a conexão é estabelecida e começa a enviar e receber comandos SMTP.
Estamos recebendo o seguinte em nossa fila do Exchange para apenas um domínio:

Eu não consigo descobrir qual é o problema. Parece que pode estar no final remoto depois do:
250 2.1.0 [email protected] OK,
Em seguida, diz:
,,Remote
o que quer que isso signifique, e então esse é o fim desse log e conexão.
Alguma ideia de como resolver este problema?
