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?
Any suggestions?

Sounds useful. I hadn't realised what 'stunnel' did beforehand..
Hopefully it'll let me see how the server that hosts my domain is
responding (or not).
At the moment I'm doing my investigation from my win10 machine...

I suspect (hope) that once I've cracked the access method to the remote

will Just Work(tm), minus the GCM aspiration ;-)

It has been a help.

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

I didn't , in the end, use `stunnel`, but it looks like the right tool
for more detailed investigation.

Ended up using plain port 25 SMTP + pwd, which wasn't advertised as
available by my domain provider. Not the full solution but a start. At
least I now have a working `send-email` that is not locked to my home
ISP connection.

While intermittently trying stuff, I was also able to get the `git
imap-send -v` settings to work (port 993). 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.
"warning: see https://aka.ms/gcm/autodetect for more information."

Maybe should raise an issue with GCM on supporting send-email and imap-send?

So port 25 to the rescue as noted. Sufficient to do work.

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.
