Sorry for the delay in reply, and thanks for the fix.
I have checked, and the problem seems to be fixed with curl 8.21.0-rc3.
For the history, curl.exe (8.21.0-rc3) outputs the following:
< 250-AUTH GSSAPI NTLM
...
> AUTH GSSAPI
< 334 GSSAPI supported
...
< 235 2.7.0 Authentication successful
> MAIL FROM:<test_at_acme.com> SIZE=164
...
This output is consistent with 8.16.0, which didn't have the regression.
Thanks,
Alexandr Timofeev
