From: Stefan Agner <ste...@agner.ch>

Sometimes sending huge patches/commits fail with

[Net::SMTP::SSL] Connection closed at /usr/lib/git-core/git-send-email
line 1320.

Running the command with --smtp-debug=1 yields to

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.

Stefan described it in his mail like this:

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.
