It's the first time I heard it referred to as "FTPES," that's probably just a made up name by the FileZilla developers that pretty much nobody else uses. I too got confused by that name though last time, so don't even use "ftps://" with lftp since that is for implicit ftps, sorry about the bad advice. For explicit TLS just open it like "ftp://"; or you don't even need to specify a protocol since ftp is the default. Using an encrypted control connection when available is also turned on by default in lftp (set ftp:use-feat yes, set ftp:ssl-allow yes). So you really don't have to do anything but open it normally like $ lftp jack.masquilier....@ftp.ocsa-data.net and you should be good to go.
