Eu tenho um servidor de email postfix e quero usar o amavis para detecção de spam e vírus. Eu segui o este tutorial para adicionar o amavis ao meu servidor de e-mail em execução. Eu adicionei ao /etc/postfix/main.cf:
content_filter = smtp-amavis:[127.0.0.1]:10024
e meu /etc/postfix/master.cf bloqueia assim:

Todos os e-mails que eu tento enviar recebem o status diferido com essas informações de registro:
Jan 19 10:28:51 mydomain postfix/smtp[2035]: BB27526F73: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=2.7, delays=0.13/0.01/0/2.5, dsn=4.5.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 id=00944-02 - Temporary MTA failure on relaying, From MTA() during fwd-connect (Negative greeting: at (eval 134) line 479.): id=00944-02 (in reply to end of DATA command))
Se eu re-enfileirar o email diferido, ele será entregue. Mas todos os novos e-mails que não foram enfileirados antes de obter o mesmo status com o mesmo problema.
Alguém tem alguma idéia de como resolver esse problema?
EDITAR: Aqui estão mais algumas linhas de meus logs também com o log depois de reenviar o email:

Ah, eu me sinto tão idiota ...
encontrou o erro. masegaloeh thx pela sua dica e desculpe por todos que perderam tempo por causa da minha estupidez ...
Acabei de fazer um comentário errado no meu master.cf que apaguei antes de postar o conteúdo aqui, então meu arquivo original master.cf travou assim:
##### Amavis inbound properties ######
127.0.0.1:10025 inet n - n - - smtpd ### stupid commend :(
-o content_filter=
-o local_recipient_maps=
Thia linha maillog
Jan 19 13:45:13 mydomain postfix/smtpd[2361]: fatal: unexpected command-line argument: ###
foi um indicador claro de que algo estava errado na sintaxe master.cf . Você já confirmou isso em sua resposta. Nesta parte, tentarei explicar por que os e-mails passam quando você os enfileira.
Quando você emite o comando postsuper - r para requeuir a mensagem, o postfix moverá o email para a fila do maildrop. Então, o daemon pickup irá "pegar" e tentar entregá-lo. Na outra parte, você desabilitou o amavis content_filter no processo de retirada (via master.cf). Então, o e-mail requeued não passará pelo amavis, portanto, não sofre mensagem de erro como acima.
