Você está se conectando ao host local via IPv6 (:: 1), mas esse endereço não faz parte da lista "mynetworks". Mude para
mynetworks = 127.0.0.0/8, < site IP & gt ;, [:: 1] / 128
e isso deve funcionar.
Eu tenho a configuração do postfix e dovecot para lidar com o correio do meu domínio. O imap parece funcionar bem ao ler o correio local, mas quando eu tento enviar um e-mail usando o telnet com o localhost e a porta smtp ele me fornece o erro de acesso negado.
[root@vps69576 ~]# telnet localhost smtp
Trying ::1...
Connected to localhost.
