Not the full solution but a start. At\nleast I now have a working `send-email` that is not locked to my home\nISP connection.\n>\n>> Maybe that helps, maybe not, it sidesteps your questions a bit, but\n>> maybe in a way where you won't need to worry about git send email.\n> It has been a help.\n>\n> Philip\n\nWhile intermittently trying stuff, I was also able to get the `git\nimap-send -v` settings to work (port 993). I did need to change the path\nto my 'Drafts' mailbox (it's not below 'Inbox.' in my Thunderbird). Only\ntested with `sslVerify = false`.\n\nThe `-v` did indicate that the GCM was being invoked, based on some\nwarning text but I haven't taken that further.\n\"warning: see https://aka.ms/gcm/autodetect for more information.\"\n>\n>> On Sat, Apr 16, 2022, 16:04 Philip Oakley wrote:\n>>\n>> This maybe a wXYz-Problem.

I'm cautious of it being\na bit of a tar pit when other solutions may be simpler (e.g. continuing\nwith the port 25 solution).\n\nThe choice of implicit vs explicit ssl is still something I haven't\nfully understood, though the explanation of the relationship between\nmethods at https://stackoverflow.com/a/29022120/717355 was useful.
