Set an IMAP Mailbox Quota (SETQUOTA)

Demonstrates the Chilkat Imap.SetQuota method, which sends the IMAP SETQUOTA command. The first argument is the quota root, the second is the resource (STORAGE or MESSAGE), and the third is the limit. The server must support the IMAP QUOTA extension.

Background: Setting a quota is an administrative operation, so the logged-in account must have permission to change it. For the STORAGE resource the limit is measured in units of 1024 octets, so a value of 500000 is roughly 500,000,000 bytes; MESSAGE instead caps the number of messages. Use GetQuotaRoot to read the current usage and limits back.
