Eu sou noob total sobre Unix e CLI. depois de pesquisar por quase 6 horas, fiquei sabendo que deveria editar a porta postfix de 25 a 587 para que a função mail () do PHP funcionasse. e aqui está a solução que eu tenho http://www.linuxmail.info/postfix-change-port/, mas não tenho certeza de como alterá-lo. como já disse que sou um noob. qualquer ajuda sobre isso será apreciada.
UPDATE1:
solução grawity me dá o seguinte erro.
