I can give you help with configuration, as can others, but as has been
pointed out you really need to know whether or not your ISP blocks
ports.

A very quick search found this for me:-
http://www.yougetsignal.com/tools/open-ports/
which I just tried out and it appears to give accurate results. I do not
know, though, if it only gives a positive response if the port is
forwarded by the router AND there is something on the network listening
on that port. If, for instance, you want to check that IMAP and IMAPS is
working then install dovecot, enable the protocols and test it. Or
apache might be easier for starters. I don't think you need to configure
anything to see a response to a web browser.

The other thing I think I should say is, I hope you're fooling around
with a test machine here, rather than one that matters to you. A test
machine can easily be a virtual machine.
