Unable to deliver more emails in the main/undeletable account.

Greetings.

As the subject says, the last email delivered in the main/undeletable mailbox was on 2015-10-29 14:00. They are all cronjobs outputs. This mailbox can send more emails to itself, but they're never delivered.

Is the storage full? I don't know. Roundcube always shows 0%/unknown.

The main email account is sending and receiving emails perfectly right now. It seems more related with the system having troubles for emailing the cron jobs outputs.

I'm gonna research further, but it seems the system can't dump the cron jobs outputs through email.

Confirmed. There's nothing bad about the email accounts. It seems that the system is not dumping cron jobs outputs by email. Very weird.

Is there any way to solve this? Thanks.
