(.NET Core C#) Delete IMAP Email

To delete an email, the "Deleted" flag must be set to 1 for each message to be deleted. You must also call Expunge or ExpungeAndClose to remove the emails marked as deleted.

Note: This example requires Chilkat v11.0.0 or greater.

bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// This example deletes email matching a criteria from Inbox.
Chilkat.Imap imap = new Chilkat.Imap();

// Turn on session logging:
imap.KeepSessionLog = true;

// Connect to an IMAP server.
// Use TLS
imap.Ssl = true;

// Set the Deleted flag for each message:
