This is a good question. I hope someone can answer it. Entering 'ssl version' in a terminal shows that the programs are there and starting correctly, but that is not necessarily the same thing as "working."How can I test that SSL support is working in 5.20 before I raise a problem to a site needing this (the site in question is gmail)
The next version of luci-251 will have openssl 1.0 (unless something goes wrong) so it would be nice to be able to confirm correct operation.
I was just able to create and send and receive mail on a gmail account with the 251pre that will be luci-251 using sylpheed.
