There are two // ways to do it: // 1) Set the flag directly by using the sequence number // Indicate that we are passing a sequence number and // not a UID: var bIsUid = false; // Set the SEEN flag = 1 to mark the email as SEEN, // or set it to 0 to mark it as not-seen. success = imap.SetFlag(i,bIsUid,"SEEN",1); if (success !== true) { console.log(imap.LastErrorText); return; } // 2) Alternatively, we can use the email object. // When an email is downloaded from the IMAP server // Chilkat will add a "ckx-imap-uid" header to the email. // This makes it possible to know the UID associated with // the email. (This is not the sequence number, which may change // from session to session, but the UID which does not change. // The SetMailFlag method is identical to SetFlag, except // it gets the UID from the ckx-imap-uid header. // For example: success = imap.SetMailFlag(email,"SEEN",1); if (success !== true) { console.log(imap.LastErrorText); return; } } // Disconnect from the IMAP server. success = imap.Disconnect(); } chilkatExample(); |
