The first service is a check on IMAP port 143 with a timeout of five seconds and it searches for a text string 'OK' which is part of the response of the IMAP server to a connection request. The second service is for IMAPS and it shows the port listing there as port 993 while it searches for a more detailed text string in 'Dovecot ready'.
