GreetingBanner is a read-only string property used to help in identifying the remote IMAP4 server for the client connection. GreetingBanner can help the user decide the appropriate actions to perform after connecting to the IMAP4 server. 

GreetingBanner is updated in the Connect method using values returned in the initial IMAP4 server response received after establishing the client connection. This generally includes information that identifies the server and its state, like: 

  * OK IMAP4rev1 Service Ready
