Eu construí um novo servidor Postfix e tenho o seguinte problema. Quando tento enviar um e-mail com o comando "Mail" de outro servidor e o destinatário está em outro domínio recebo "Relay access denied" nos logs do servidor Postfix.
No entanto, funciona quando eu o envio para o mesmo domínio com o comando Mail ou ao usar o Thunderbird.
Meu entendimento é que, se o servidor estiver em "mynetworks", ele deve funcionar sem autenticação, mas parece que estou fazendo algo errado.
O seguinte é a saída do postconf -n

Eu fiz sovlve. Eu usei a sintaxe errada para mynetworks Eu tentei
mynetworks = ['127.0.0.1', '192.168.1.0/24']
mynetworks = '127.0.0.1', '192.168.1.0/24'
mas precisava ser
mynetworks = 127.0.0.1 192.168.1.0/24
mesmo que o comentário no main.cf logo antes seja
# MYNETWORKS = ['xx.xx.xx.xx', 'xx.xx.xx.0/24', ...]
