Returns a reference to the key-value list of the mail server capabilities.

Return Value

The key-value list of the mail server capabilities, or a null reference (Nothing in Visual Basic) if the capabilities list is not available.

Remarks

You should already be connected to the IMAP4 server in order to use this method.

In the returned StringDictionary, each key is a capability name (always lowercase) and its value is an empty string (because IMAP4's capabilities have no parameters).

Exceptions

Example

This sample displays the list of all capabilities supported by the mail server.
