Capabilities Property

Description

Collection of strings that contains the protocol extensions advertised as supported by the server. Values are initialized during login.

Property type

Read-only property

Syntax

Visual Basic
Public Property Capabilities As DartStrings

Remarks

Read-only (but you can remove Strings in the collection).

As part of the Login process, every IMAP server announces the capabilities of that server implementation. For example, the following strings may be added to the Imap.Capabilities string collection during login:

IMAP4
IMAP4REV1
NAMESPACE
IDLE
SCAN
SORT
MAILBOX-REFERRALS
LOGIN-REFERRALS
X-NOOP-DUPLICATE-SELECT
AUTH=LOGIN
THREAD=ORDEREDSUBJECT

Unlike the SMTP Control (which uses the Capabilities property to optimize the transmission of mail), the IMAP Control provides these values for informational purposes only.
