Eu tenho lido muito sobre o assunto, mas infelizmente não consigo fazê-lo funcionar. Eu tenho um Centos 6.3 com o sendmail instalado. A caixa é usada como um servidor BackupPC e talvez um servidor samba depois.
Desejo encaminhar todos os e-mails para o servidor SMTP do ISP e não quero que o e-mail seja entregue localmente. A caixa BackupPC não hospeda o email que o seu ISP faz, eu não quero me envolver em sua hospedagem de email, eu só quero que eles recebam suas notificações do BackupPC.
Parece que esse comando deve cuidar dele FEATURE('nullclient', 'server.fctherapy.com') dnl , mas quando executar m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
Eu recebo este erro:
m4:/etc/mail/sendmail.mc:177: ERROR: end of file in string.
Eu tentei diferentes combinações da configuração nullclient mas nenhum sucesso abaixo é minha configuração do sendmail

Pode ser que recortar e colar estragou alguma coisa, mas quando vejo a última linha da macro M4, parece que ocorreu alguma formatação incorreta / configuração de tipo:
FEATURE('nullclient’, 'server.example.com’) dnl
O recurso deve ser rodeado apenas de backtick único (acento grave, ` ) e ' (acento agudo, ´ ) em vez do que parece ser uma citação de fechamento simples do tipo ' (código HTML ’ ):
