* Setting up `send-email` for SSL, and then using GCM (Git Credential Manager) [not found] <10919180-85ea-2172-28df-b718cdbdf783@iee.email> @ 2022-04-16 11:38 ` Philip Oakley [not found] ` <CACBZZX6d4f3TZnytxXy5_62EVbUL7UObyhR7eR3ApsECeQ=6sA@mail.gmail.com> 0 siblings, 1 reply; 3+ messages in thread From: Philip Oakley @ 2022-04-16 11:38 UTC (permalink / raw) To: Git List This maybe a wXYz-Problem. But I'm stuck at getting SSL to work with `send-email`. I'm trying to update both my home Windows PC (win10) and my Ubuntu travel laptop (an old-Acer-i5) `send-email` setup/config to use my personal email domain (with authentication), rather than my old home ISP locked (no auth) connection, but I'm struggling. Z) Does the GCM (Git Credential Manager) integrate well with send-email, and what guidance is available for setting up and debugging the `send-email` configuration? Y) It's not clear what I should see in the terminal window in either Git-for-Windows or Ubuntu when testing the `git send-email` command - without/with using GCM. w) Some back story. I set up my existing telephone-line-locked home send-email config many years ago around the time of dial-up/ADSL. My router logs into my ISP giving me an open port 25 for SMTP (though doesn't advertise that any more). My config for the ISP is simple, needing only the `smtpServer, smtpServerPort`, and my `from, suppressfrom, & chainreplyto` settings. It works for both the Win PC and my Ubuntu laptop, but I can only use this when at home. I also have a personal email domain (iee.email) whose authentication works with Thunderbird for the WinPC at home, and the Ubuntu laptop at home and when away from home. I'd like to be able to use ` send-email` via the personal email domain on the laptop when away from home (final goal), and also match that `send-email` use on the Win PC (which would also allow easy switching ISP when needed). X) Where I've reached. I've discovered `sendemail.identity`, so at least I can have both configurations available for selection [7]. I've added the --smtp-debug=1` with little insight. I've hit a brick wall with respect to establishing the connection (I think). It's not clear if any authentication (password stuff) has started. I fail to get the "<<<220 xxxxx server ready" reply that my ISP identity gives, rather I get "Net::SMTP: Net::Cmd::getline(): unexpected EOF on command channel: Connection reset by peer ... Unable to initialize SMTP properly. Check config and use --smtp-debug. VALUES: server=smtp.hosts.co.uk encryption= hello=localhost.localdomain port=465" I've added below the terminal responses [1,3] and extracts of the config [2,4] for my test 'cover-letter'. Plus my Thunderbird settings [5] for comparison. Git build [6]. Domain provider advice [8]. Thoughts: Maybe the setting I need for `git-end-email` don't match those used by Thunderbird; Is there extra debug info if I set some extra parameters. Maybe some other tool can provide insight into what's failing?

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.
