(.NET Core C#) IMAP Delete Old Email (before a specified date)Demonstrates how to delete email older than a particular date. 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. Chilkat.Imap imap = new Chilkat.Imap(); // Connect to an IMAP server. // Use TLS imap.Ssl = true; imap.Port = 993; // Use your IMAP server domain. This example success = imap.Connect("imap.example.com"); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } // Login success = imap.Login("myLogin","myPassword"); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } // Select an IMAP mailbox success = imap.SelectMailbox("Inbox"); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } // Get message ID's for emails older than 1/1/2025 bool fetchUids = true; Chilkat.MessageSet messageSet = new Chilkat.MessageSet(); success = imap.QueryMbx("SENTBEFORE 01-Jan-2025",fetchUids,messageSet); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } // If desired, we can examine the Subject of each email to be deleted.. Chilkat.Email email = new Chilkat.Email(); int i = 0; int count = messageSet.Count; bool headerOnly = true; while (i < count) { success = imap.FetchEmail(headerOnly,messageSet.GetId(i),true,email); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } Debug.WriteLine(email.LocalDateStr); Debug.WriteLine(email.Subject); i = i + 1; } // Set the Deleted flag for each message: success = imap.SetFlags(messageSet,"Deleted",1); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } // Expunge and close the mailbox. success = imap.ExpungeAndClose(); if (success == false) { Debug.WriteLine(imap.LastErrorText); return; } // Disconnect from the IMAP server. success = imap.Disconnect(); |
