Solução encontrada, o dovecot foi mal configurado. E remover essa linha faz o servidor funcionar bem
mynetworks = 10.10.0.0/24, 127.0.0.0/8

No pombal eu só mudei esta linha
mail_home = maildir:/var/spool/mail/%u
Eu também tentei
mail_location = maildir:/var/spool/mail/%u
Quando tento enviar um email em vez de usar / var / spool / mail tente usar (e falhar) o / root / Maildir! Onde está o meu conf errado? Por que não usar o / var / spool / mail como eu configuro? Eu tentei sem selinux mas a mesma coisa .. Distro é o mais recente centos 7
