Why does git-imap-send seem to be sending HTTP to an IMAP connection?

I hope that I'm not making some blatantly obvious mistake here, but when attempting to use git imap-send, in the command git format-patch --signoff --stdout --attach --root HEAD | git imap-send -v, I get this (error repeated once for each patch):

$ git format-patch --signoff --stdout --attach --root HEAD | git imap- 
send -v

It seems to me that git imap-send is attempting to send HTTP data to my IMAP server. All the documentation I've read seems says nothing about this behavior, and imap-send uses normal IMAP. If this is the case, what is going on, and more importantly, how can it be fixed?

Git version: 2.7.4

OS: Linux Mint 18.3

Git configuration:

imap.host=imap://mail.tdstoragebay.com (internal server)
imap.port=143
imap.folder=INBOX
Solution

  • There have been a few imap-send related fixes since Git 2.7.4

    Notably:

    • commit d2d07ab "imap-send: Tell cURL to use imap:// or imaps://" (Git 2.10.2)
    • commit 690307f "imap-send: add wrapper to get server credentials if needed " (Git 2.15.0)

    Any of those fixes could have an impact in your case.

    "git imap-send"(man) used to ignore configuration variables like core.askpass; this has been corrected with Git 2.30 (Q1 2021),

    See commit 5021236 (01 Dec 2020) by Nicolas Morey-Chaisemartin (nmorey).

    imap-send: parse default git config

    Reported-by: Philippe Blain

    git imap-send git config(man) does not parse the default settings and thus ignore core.askpass value.

    Rewrite config parsing to support core settings.
