Thanks very much for the informative and detailed reply, Jamon. Following your example, I've now managed to get server certificate validation and ssl fingerprinting to work on Rogers, Office365, and Gmail (both pop and imap). I'll have to learn someday the ins and outs of how it all works, but I'm pleased to say that I'm up and running on all counts, and have now officially switched from fetchmail to getmail. (But I'm hanging on to my .fetchmailrc just in case.)
