MailKit An IMAP client that can be used to retrieve messages from a server. The class supports both the "imap" and "imaps" protocols. The "imap" protocol makes a clear-text connection to the IMAP server and does not use SSL or TLS unless the IMAP server supports the STARTTLS extension. The "imaps" protocol, however, connects to the IMAP server using an SSL-wrapped connection. Asynchronously enable compression over the IMAP connection. Asynchronously enables compression over the IMAP connection. If the IMAP server supports the extension, it is possible at any point after connecting to enable compression to reduce network bandwidth usage. Ideally, this method should be called before authenticating. An asynchronous task context. The cancellation token. The has been disposed. The is not connected. Compression must be enabled before a folder has been selected. The IMAP server does not support the COMPRESS extension. The operation was canceled via the cancellation token. An I/O error occurred. The server replied to the COMPRESS command with a NO or BAD response. An IMAP protocol error occurred. Asynchronously enable the QRESYNC feature. Enables the QRESYNC feature. The QRESYNC extension improves resynchronization performance of folders by querying the IMAP server for a list of changes when the folder is opened using the method. If this feature is enabled, the event is replaced with the event. This method needs to be called immediately after calling one of the Authenticate methods, before opening any folders. An asynchronous task context. The cancellation token. The has been disposed. The is not connected. The is not authenticated. Quick resynchronization needs to be enabled before selecting a folder. The IMAP server does not support the QRESYNC extension. The operation was canceled via the cancellation token. An I/O error occurred.

Asynchronously identify the client implementation to the server and obtain the server implementation details. Passes along the client implementation details to the server while also obtaining implementation details from the server. If the is null or no properties have been set, no identifying information will be sent to the server. Security Implications This command has the danger of violating the privacy of users if misused. Clients should notify users that they send the ID command. It is highly desirable that implementations provide a method of disabling ID support, perhaps by not calling this method at all, or by passing null as the argument. Implementors must exercise extreme care in adding properties to the . Some properties, such as a processor ID number, Ethernet address, or other unique (or mostly unique) identifier would allow tracking of users in ways that violate user privacy expectations and may also make it easier for attackers to exploit security holes in the client.

The cancellation token. The has been disposed. Asynchronously ping the IMAP server to keep the connection alive. The NOOP command is typically used to keep the connection with the IMAP server alive. When a client goes too long (typically 30 minutes) without sending any commands to the IMAP server, the IMAP server will close the connection with the client, forcing the client to reconnect before it can send any more commands. The NOOP command also provides a great way for a client to check for new messages. When the IMAP server receives a NOOP command, it will reply to the client with a list of pending updates such as EXISTS and RECENT counts on the currently selected folder. To receive these notifications, subscribe to the and events, respectively. For more information about the NOOP command, see rfc3501. An asynchronous task context. The cancellation token.

The server replied to the NOOP command with a NO or BAD response. The server responded with an unexpected token. Asynchronously toggle the into the IDLE state. When a client enters the IDLE state, the IMAP server will send events to the client as they occur on the selected folder. These events may include notifications of new messages arriving, expunge notifications, flag changes, etc. Due to the nature of the IDLE command, a folder must be selected before a client can enter into the IDLE state. This can be done by opening a folder using or any of the other variants. While the IDLE command is running, no other commands may be issued until the is cancelled. It is especially important to cancel the before cancelling the when using SSL or TLS due to the fact that cannot be polled. An asynchronous task context.

All exceptions thrown by the handler are considered fatal and will force-disconnect the connection. If a non-fatal error occurs, set it on the property. An IMAP untagged response handler. Most IMAP commands return their results in untagged responses. IMAP command status. An IMAP IDLE context. An IMAP IDLE command does not work like normal commands. Unlike most commands, the IDLE command does not end until the client sends a separate "DONE" command. In order to facilitate this, the way this works is that the consumer of MailKit's IMAP APIs provides a 'doneToken' which signals to the command-processing loop to send the "DONE" command. Since, like every other IMAP command, it is also necessary to provide a means of cancelling the IDLE command, it becomes necessary to link the 'doneToken' and the 'cancellationToken' together.

An IMAP notification event. An IMAP event notification for expunged messages. If the expunged message or messages are in the selected mailbox, the server notifies the client using (or if the QRESYNC extension has been enabled via or ). If the expunged message or messages are in another mailbox, the and properties will be updated and the appropriate and events will be emitted for the relevant folder. If the QRESYNC extension is enabled, the property will also be updated and the event will be emitted. if a client requests with the mailbox specifier, the meaning of a message index can change at any time, so the client cannot use message indexes in commands anymore. The client MUST use API variants that take or a . The meaning of ** can also change when messages are added or expunged. A client wishing to keep using message indexes can either use the mailbox specifier or can avoid using the event entirely. An IMAP event notification for message flag changes. If the notification arrives for a message located in the currently selected folder, then that folder will emit a event as well as a event with an appropriately populated . On the other hand, if the notification arrives for a message that is not located in the currently selected folder, then the events that are emitted will depend on the of the IMAP server. If the server supports the capability (or the capability and the client has enabled it via ), then the event will be emitted as well as the event (if the latter has changed). If the number of seen messages has changed, then the event may also be emitted. If the server does not support either the capability nor the capability and the client has not enabled the later capability via , then the server may choose only to notify the client of changes by emitting the event. An IMAP event notification for message annotation changes. If the notification arrives for a message located in the currently selected folder, then that folder will emit a event as well as a event with an appropriately populated . On the other hand, if the notification arrives for a message that is not located in the currently selected folder, then the events that are emitted will depend on the of the IMAP server. If the server supports the capability (or the capability and the client has enabled it via ), then the event will be emitted as well as the event (if the latter has changed).

AN IMAP event notification for folders that have been created, deleted, or renamed. These notifications are sent if an affected mailbox name was created, deleted, or renamed. As these notifications are received by the client, the apropriate will be emitted: , , or , respectively. If the server supports , granting or revocation of the right to the current user on the affected folder will also be considered folder creation or deletion, respectively. If a folder is created or deleted, the folder itself and its direct parent (whether it is an existing folder or not) are considered to be affected. An IMAP event notification for folders who have had their subscription status changed. This event requests that the server notifies the client of any subscription changes, causing the or events to be emitted accordingly on the affected .

Otherwise, MailKit implements this operation by first searching for the full list of message uids in the folder that are marked for deletion, unmarking the set of message uids that are not within the specified list of uids to be be expunged, expunging the folder (thus expunging the requested uids), and finally restoring the deleted flag on the collection of message uids that were originally marked for deletion that were not included in the list of uids provided. For this reason, it is advisable for clients that wish to maintain state to implement this themselves when the IMAP server does not support the UIDPLUS extension. For more information about the UID EXPUNGE command, see rfc4315. Normally, a event will be emitted for each message that is expunged.

Allows subclass implementations to override the type of stream created for use with the GetMessage, GetBodyPart and GetStream methods. This could be useful for subclass implementations that intend to implement support for caching and/or for subclass implementations that want to use temporary file streams instead of memory-based streams for larger amounts of message data. Subclasses that implement caching using this API should wait for before adding the stream to their cache. Streams returned by this method SHOULD clean up any allocated resources such as deleting temporary files from the file system. The will not be available for the various GetMessage(), GetBodyPart() and GetStream() methods that take a message index rather than a . It may also not be available if the IMAP server response does not specify the UID value prior to sending the literal-string token containing the message stream. The stream. The unique identifier of the message, if available. The section of the message that is being fetched. The starting offset of the message section being fetched. The length of the stream being fetched, measured in bytes. Commit a stream returned by . Commits a stream returned by . This method is called only after both the message data has successfully been written to the stream returned by and a has been obtained for the associated message. For subclasses implementing caching, this method should be used for committing the stream to their cache. Subclass implementations may take advantage of the fact that allows returning a new reference if they move a file on the file system and wish to return a new based on the new path, for example.

The "smtp" protocol makes a clear-text connection to the SMTP server and does not use SSL or TLS unless the SMTP server supports the STARTTLS extension. The "smtps" protocol, however, connects to the SMTP server using an SSL-wrapped connection. The connection established by any of the Connect methods may be re-used if an application wishes to send multiple messages to the same SMTP server.

The exception that is thrown when there is an error during the SSL/TLS handshake. The exception that is thrown when there is an error during the SSL/TLS handshake. When this exception occurrs, it typically means that the IMAP, POP3 or SMTP server that you are connecting to is using an SSL certificate that is either expired or untrusted by your system. Often times, mail servers will use self-signed certificates instead of using a certificate that has been signed by a trusted Certificate Authority. When your system is unable to validate the mail server's certificate because it is not signed by a known and trusted Certificate Authority, this exception will occur. You can work around this problem by supplying a custom and setting it on the client's property. Most likely, you'll want to compare the thumbprint of the server's certificate with a known value and/or prompt the user to accept the certificate (similar to what you've probably seen web browsers do when they encounter untrusted certificates).

When multiple message summaries are being fetched from a remote folder, it is possible that the connection will drop or some other exception will occur, causing the Fetch method to fail, requiring the client to request the same set of message summaries again after it reconnects. This is obviously inefficient. To alleviate this potential problem, this event will be emitted as soon as the successfully retrieves the complete for each requested message. The Fetch methods will return a list of all message summaries that any information was retrieved for, regardless of whether or not all of the requested items were fetched, therefore there may be a discrepency between the number of times this event is emitetd and the number of summary items returned from the Fetch method.

Get or set whether connecting via SSL/TLS should check certificate revocation. Gets or sets whether connecting via SSL/TLS should check certificate revocation. Normally, the value of this property should be set to true (the default) for security reasons, but there are times when it may be necessary to set it to false. For example, most Certificate Authorities are probably pretty good at keeping their CRL and/or OCSP servers up 24/7, but occasionally they do go down or are otherwise unreachable due to other network problems between the client and the Certificate Authority. When this happens, it becomes impossible to check the revocation status of one or more of the certificates in the chain resulting in an being thrown in the Connect method. If this becomes a problem, it may become desirable to set to false. true if certificate revocation should be checked; otherwise, false.

Gets or sets the SSL and TLS protocol versions that the client is allowed to use. By default, MailKit initializes this value to support only TLS v1.1 and greater and does not support TLS v1.0 or any version of SSL due to those protocols no longer being considered secure. This property should be set before calling any of the Connect methods. The SSL and TLS protocol versions that are supported. Gets or sets the client SSL certificates.

Get or set whether connecting via SSL/TLS should check certificate revocation. Gets or sets whether connecting via SSL/TLS should check certificate revocation. Normally, the value of this property should be set to true (the default) for security reasons, but there are times when it may be necessary to set it to false. For example, most Certificate Authorities are probably pretty good at keeping their CRL and/or OCSP servers up 24/7, but occasionally they do go down or are otherwise unreachable due to other network problems between the client and the Certificate Authority. When this happens, it becomes impossible to check the revocation status of one or more of the certificates in the chain resulting in an being thrown in the Connect method. If this becomes a problem, it may become desirable to set to false. true if certificate revocation should be checked; otherwise, false.

This usually involves downloading the first 512 bytes for text/plain message bodies and the first 16 kilobytes for text/html message bodies. If a message contains both a text/plain body and a text/html body, then the text/plain content is used in order to reduce network traffic. A macro for fetching the , , , and values.

When the option is specified, it extends the list of metadata tag values returned by the GetMetadata() call. For each specified in the the GetMetadata() call, the method returns the value of the specified metadata tag (if it exists), plus all metadata tags below the specified entry up to the specified depth. Three values are allowed for : 0 - no entries below the specified metadata tag are returned. 1 - only entries immediately below the specified metadata tag are returned. - all entries below the specified metadata tag are returned. Thus, a depth of 1 for a tag entry of "/a" will match "/a" as well as its children entries (e.g., "/a/b"), but will not match grandchildren entries (e.g., "/a/b/c"). If the Depth option is not specified, this is the same as specifying 0. The depth. is out of range. Get or set the max size of the metadata tags to request.
