mbox for IMAP Workflow user

[big]

Hi,
On 11.5.10.2 for Workflow mailer we have:



Is there any concurrent program or any solution to resize mbox? On healthy system I have around 530M as mbox size.

Or delete messages from mbox when they are processed.

Thanks and regards.

It seems you are using Dovecot a similar thing as an IMAP server.
he mbox file contains all the messages of a single mailbox.
It is specific to Dovecot, a 3rd party thing.
https://doc.dovecot.org/configuration_manual/mail_location/mbox/ -> Read the manual.
Probably, you will use doveadm - Dovecot's administration utility to manage these things..
