I don’t have the luxury of having access to a useable computer from a site remote to my server, but I still need to test my email server, the TLS/SSL setup, smtp and smtpd. There are some remote test sites that also want a valid email and password! But I’m a bit reluctant obviously. I suspect my site is not quite right, but can’t find a way to test it, and to explain results of tests. Especially the TLS/SSL ones. Does anyone know of any reliable testing options?
