A catch up email to report where I got to; some successes and some remaining todos. Details in-line with original query.

Not the full solution but a start.

I did need to change the path to my 'Drafts' mailbox (it's not below 'Inbox.' in my Thunderbird). Only tested with `sslVerify = false`. The `-v` did indicate that the GCM was being invoked, based on some warning text but I haven't taken that further.

I've still to delve into that part of the code. I'm cautious of it being a bit of a tar pit when other solutions may be simpler (e.g. continuing with the port 25 solution). The choice of implicit vs explicit ssl is still something I haven't fully understood, though the explanation of the relationship between methods at https://stackoverflow.com/a/29022120/717355 was useful. How the implicit ssl is started is something I'm still unfamiliar with. >> Unable to initialize SMTP properly.
