Uma conta parou de receber emails - postfix / dovecot

Question

Meu servidor estava funcionando corretamente, mas agora uma conta não pode receber e-mails. Os remetentes estão trabalhando na mesma conta. Eu tenho o postfix / dovecot instalado no Ubuntu com este guia: link .

Não há erros no arquivo mail.err. Informações para verificar no log: O problema está no ID de email: [email protected]. Eu enviei um email para [email protected] de [email protected] para verificar. '[email protected]' tem encaminhadores: [email protected] & [email protected]

Uma coisa que notei no log é: nrcpt = 1 (fila ativa)  ou nrcpt = 4 (fila ativa)

Algum log do arquivo mail.log é:
