Aqui está um exemplo
Se você usar sendmail , coloque seus domínios em /etc/mail/local-host-names e /etc/mail/generics-domains .
Depois disso, no /etc/mail/genericstable , adicione os e-mails de seus usuários neste formato:
myuser [email protected]
myotheruser [email protected]
No /etc/mail/virtusertable adicione a reversão:
[email protected] myuser
[email protected] myotheruser
No /etc/mail/sendmail.mc use esta configuração, alterando o nome do domínio para o seu domínio principal:
