if there are no security messages in the MVS syslog,
here is one other place i might look:

if the syslogd daemon is running, usually FTPD
(depending on its own config file) will write messages
concerning the connections it permits(or denys) into
a file specified by /etc/syslog.conf. these are usually
in the /tmp directory and can be browsed by using ish.
they are usually mixed with messages from other
daemons but you might find a cluster of them concerning
your port 990 connection that could be useful.
