Configurando o servidor de email com o host de retransmissão

Question

Portanto, a porta 25 no meu servidor de e-mail está bloqueada e agora estou tentando configurar meu servidor de e-mail com uma retransmissão SMTP para enviar e-mails com dynu.com. Mas eu continuo recebendo as mensagens de erro abaixo quando eu tento enviar um e-mail do janela do terminal.

No master.cf eu configurei o seguinte

465 inet n - n - - smtpd

No main.cf eu configurei isso

myhostname = rajohan.no
mydestination = localhost, rajohan.no, localhost.rajohan.no
mynetworks = 127.0.0.0/8 192.168.0.0/24 [::ffff:127.0.0.0]/104 [::1]/128

smtpd_sasl_auth_enable = yes
smtpd_sasl_password_maps = hash:/etc/postfix/sasl_password

relayhost = [relay.dynu.com]:465
smtpd_generic_maps = hash:/etc/postfix/generic

Em sasl_password eu tenho

relay.dynu.com
[email protected] mypassword

Em genérico eu tenho

[email protected]         [email protected]
[email protected]      [email protected]
[email protected]    [email protected]
[email protected]   [email protected]

Answer 1

Seu arquivo sasl_password deve ser formatado assim e corresponder ao da diretiva relayhost :

[host]:Port USERNAME:PASSWORD

Então, o seu pareceria assim:

[relay.dynu.com]:465 [email protected]:mypassword

Então você precisa fazer o hash do arquivo: sudo postmap /etc/postfix/sasl_password

Agora, você criou um arquivo: /etc/postfix/sasl_password.db

Altere as seguintes diretivas no seu main.cf (remova o d):

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password

Não se esqueça de reiniciar o postfix.
