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