6.4.3. EXPUNGE Command
Arguments: none
Responses: untagged responses: EXPUNGE
Result: OK - expunge completed
NO - expunge failure: can't expunge (e.g. permission
denied)
BAD - command unknown or arguments invalid
The EXPUNGE command permanently removes from the currently
selected mailbox all messages that have the \Deleted flag set.
Before returning an OK to the client, an untagged EXPUNGE response
is sent for each message that is removed.
Example: C: A202 EXPUNGE
S: * 3 EXPUNGE
S: * 3 EXPUNGE
S: * 5 EXPUNGE
S: * 8 EXPUNGE
S: A202 OK EXPUNGE completed
Note: in this example, messages 3, 4, 7, and 11 had the
\Deleted flag set. See the description of the EXPUNGE
response for further explanation.
