No, it's not a bug. As you know maildir storage format stores one email _per file_. virtual_mailbox_limit is a _per file_ size restriction. With maildir storage it will prevent individual emails (individual files) greater than (default: 51200000) in size being written into the maildir directory, but it will not limit the size of the parent directory, which is what I think you're referring to as a "user mailbox". This restriction has its roots in mbox format storage. Since mbox is one single file, virtual_mailbox_limit has the effect of a simple quota enforcer, as it won't write new mail to an mbox file if the resulting file size would be greater than (default: 51200000). virtual_mailbox_limit is essentially useless with maildir storage. As others mentioned you need to use a delivery agent that can enforce quotas with maildir storage, or you need to enable filesystem quotas if your filesystem supports quotas (many do not). -- Stan
