Code:
tcp4       0      0 *.995                  *.*                    LISTEN
Ok it is there LISTENing.

To check whether packets are arriving on that port open up another xterm or console
and start tcpdump.:
Code:
# tcpdump -ni fxp0 -vv 'port 995'
Replace the 'fxp0' by the NIC which you have. Then open up the TLS/SSL connection and see whether tcpdump shows anything arriving.

If they arrive, check your firewall rules, that you are not accidently blocking port 995 traffic.

In case you are using 'pf' and a 'block log all' rule, you can check packet blockage with
Code:
# tcpdump -eni pflog0 -s 128
In yet another console, of course.
