cerb.mail.mailbox.errors
Description
This counter tracks protocol errors when checking each mailbox, broken down by error status code.
Use it to catch a mailbox whose credentials have expired or whose host has changed – the status dimension distinguishes an authentication failure from a connection problem.
It also backs the usage: quick search filter on mailbox worklists – for instance, usage:(errors:>0) returns mailboxes that have ever had an error.
