All good thoughts/questions. I have two suggestions to add:

 1. As an immediate work-around, running "imap-send --no-curl" may work. 
    That will at least get this case working while we debug.

 2. Setting GIT_TRACE_CURL=1 may dump more verbose information. But one
    caveat: if you get as far as authenticating, then the trace will
    contain your password. We redact HTTP auth from the trace output,
    but not imap ones.
