supportsFlagging method

bool supportsFlagging()

Determines if message flags such as \Seen can be stored.

POP3 servers do not support message flagging, for example. Note that even on POP3 servers the \Deleted "flag" can be set. However, messages are really deleted and cannot be retrieved after marking them as deleted after the current POP3 session is closed.

Implementation

bool supportsFlagging() {
  return _incomingMailClient.supportsFlagging();
}
