Hello
Recently, I have had trouble using git send-email to send a patchset.
After the confirmation to send the email I get the following:
Send this email? ([y]es|[n]o|[q]uit|[a]ll): y
[Net::SMTP::SSL] Connection closed at /usr/lib/git-core/git-send-email
line 1320.
fatal: 'send-email' appears to be a git command, but we were not
able to execute it. Maybe git-send-email is broken?
This message first appeared when I tried to send a 19 commit patchset
via 'git send-email HEAD~19'. It also fails when I try to format-patch
and send the patchset separately via 'git send-email 0001...'
Oddly enough, it works when I send anything other than 19 commits
for example 'git send-email HEAD~1' or 'git send-email HEAD~20'
I thought it was something with the gmail servers but I was able to send
the patchset by downgrading a couple perl packages
warning: downgrading package perl (5.22.0-1 => 5.20.2-1)
warning: downgrading package perl-net-ssleay (1.68-2 => 1.67-1)
Note perl-net-ssleay depends on perl 5.22 so I can't isolate which
package but I can consistently get the failure with the newest packges
and it works fine with the downgraded packages.
Running Arch Linux
git 2.4.5
perl 5.22.0
perl-authen-sasl 2.16
perl-mime-tools 5.505
perl-net-smtp-ssl 1.03
.gitconfig
[sendemail]
smtpEncryption = tls
smtpServer = smtp.gmail.com
smtpUser = juston.h.li@gmail.com
smtpServerPort = 587

I believe that this is due to gmail not allowing the email. I think
there are two ways to fix this:
1. Temporarily enable less secure apps for your gmail account while
you send the email [see
here](https://support.google.com/accounts/answer/6010255?hl=en).
2. Setup multi-factor authentication on your account and create an
app specific password for git-send-email [see
here](https://support.google.com/accounts/answer/185833?hl=en)
Obviously the second method is more secure. I have had success with
both of these techniques.

Just got a similar message here, without the fatal part, just:
[Net::SMTP::SSL] Connection closed at /usr/lib/git-core/git-send-email
line 1320.
It seems that only one patch is causing the problem (in my case the
first after the cover letter). I use TLS too and send it over a postfix
SMTP server I maintain myself. The postfix log shows this:
postfix/smtpd[8535]: lost connection after DATA (16357 bytes) from
unknown[x.y.z.z]
postfix/smtpd[8535]: disconnect from unknown[x.y.z.z]
So it seems that the client side disconnects?
I rerun the command with --smtp-debug=1
...
Net::SMTP::SSL=GLOB(0x1fb3558)>>> +MODULE_LICENSE("GPL");
Net::SMTP::SSL=GLOB(0x1fb3558)>>> --
Net::SMTP::SSL=GLOB(0x1fb3558)>>> 2.4.5
Net::SMTP::SSL: Net::Cmd::datasend(): unexpected EOF on command channel:
at /usr/lib/git-core/git-send-email line 1320.
[Net::SMTP::SSL] Connection closed at /usr/lib/git-core/git-send-email
line 1320.
It seems to me that there is a size limit, after cutting down the patch
to ~16K, sending started to work. I cut it twice, once by removing lines
from the head and once from the bottom, in both cases at the size of
around 16K I could send the patch.

Same versions here, unfortunately I can't downgrade because I recently
cleared my package cache :-(

I found a work-around by using datasend line by line, which did the job
for me:
Altering /usr/lib/git-core/git-send-email, around line 1320:
$smtp->datasend("$header\n") or die $smtp->message;
my @lines = split /^/, $message;
foreach my $line (@lines) {
$smtp->datasend("$line") or die $smtp->message;
}
