Olá Alexandre.
Tente rejeitar os "User unknown" no momento da conexão de seu provedor
com seu servidor. Vc está aceitando o email para verificar depois se a
conta existe ou não. Para tanto, vc tem q definir uma
tabela/hash/banco/ldap listando todas suas contas, ex:
main.cf:
----------------------------------------------
local_recipient_maps = hash:/usr/local/etc/postfix/recipients
unknown_local_recipient_reject_code=550
smtpd_recipient_restrictions = ..., outras regras,...,
reject_unlisted_recipient ...
----------------------------------------------
Acerte seu "local_recipient_maps" e adicione "reject_unlisted_recipient"
ao smtpd_recipient_restrictions

Boa tarde
Estou com um problema que ao enviar email para meu domínio caso a
caixa não exista o remetente não recebe o erro.
Fim um teste e dentro da minha rede e ai funciona, o remetente recebe
a informação que o destinatário foi recusado, alguém pode me dar alguma
dica.
