Get mailtransport with kolabnow to work

when connecting to smtps:// the command will silently fail,
with wireshark spewing out a cryptic "5.5.2 command not recognized".

The magic commandline (that works) is:
    curl smtp://smtp.kolabnow.com:587 -v --mail-from
    "$USER" --mail-rcpt "$USER" --ssl -u
    $USER.ch:$PW -T alternative.mbox -k --anyauth
