Our mailserver is not working any more. Short: we messed it up.
Your duty will be make all componentes working together like charme.
procmail //Your system mailbox: /var/mail/root ??
We run small digital ocean droplet with several domains.
The issues arised after we installed LDAP server trough webmin. Did not work and we disabled it. At least the issues showed up shortly after that approach.
We like you to exaime the config files, pathes and permissions and give recommendation.
Please not we cannot provide shell access to server.
