Nosso VPS já estava configurado, mas meu colega de trabalho instalou acidentalmente o sendmail. O postfix ficou louco e muitos erros apareceram, o postfix se recusou a ser executado. Desinstalei o sendmail, reconfigurei / reinstalei o postfix mas agora o nosso servidor pode enviar mensagens, mas não receber.
Usando o roundcube como um cliente. Os e-mails não são devolvidos ao remetente por algum motivo, não tenho certeza do que posso fazer? Parece que os e-mails estão chegando, mas não são mostrados em lugar algum, também não consigo encontrá-los em / var / mail em qualquer lugar. Onde estão os logs localizados?
Obrigado por qualquer conselho.
Aqui está o arquivo main.cf :
