Get an IMAP Mailbox Quota

Demonstrates the Chilkat Imap.GetQuota method, which sends the IMAP GETQUOTA command for a quota root and returns the server response as JSON. The server must advertise the IMAP QUOTA extension. This example queries the default quota root.

Tip: JSON parsing code for this result can be generated at Chilkat Tools.

Background: Mail servers often cap how much storage an account may use. The IMAP QUOTA extension reports the current usage and limit for a quota root — a scope that may cover one mailbox or a whole account. Reading it lets an application warn a user who is nearing their limit, or refuse to append large messages that would exceed it. Check HasCapability for QUOTA first, since not all servers support it.
