vdu [flags] username1 username2
example: vdu fred lucy
If no username is given, information for all email usernames under the account will be listed, one mail account per line.
If username(s) are supplied in the command, only the information for those accounts will be listed.
For example, you may see:
fred 1 4 0 0 0 0 20 (this would be a POP/IMAP account)
lucy(disabled) 0 0 0 0 0 0 16 (this would be a forwarding alias)
Each line from vdu contains the following items:
1. The virtual username (with a notation of "-" or "(disabled)" for aliases)
2. The number of new messages
3. The number of kiloBytes in new messages
4. The number of unread messages
5. The number of kiloBytes in unread messages
6. The number of read messages
7. The number of kiloBytes in read messages
8. The number of kiloBytes in overhead files (all accounts will have overhead)
See below for definitions of New, Unread, and Read email:
New messages are messages that have not yet been downloaded or accessed in any manner.
Unread indicates email that has been accessed using, for example, SSH or POP3 Scan Mailbox, where the headers are downloaded, but the message bodies themselves are not.
Read messages are copies of messages left on the server after you have downloaded the email.
Supplying "-a" or "--all" as a flag will result in each IMAP folder being shown as well. Each IMAP folder has the same format as the base account.
For example, issuing the command:
vdu -a imapbox
will show the details for the imap folders under the imapbox:
imapbox 0 0 0 0 1 4 40 Drafts 0 0 0 0 0 0 20 Trash 0 0 0 0 0 0 28 Sent 0 0 0 0 1 4 28
