My mandrill smtp is working fine. I am on 0217f50f1219585ad9f7f65a54cc545c2723f98eI have enabled

  ENABLE_INSTRUCTOR_EMAIL: True
  REQUIRE_COURSE_EMAIL_AUTH: False

and sent email to myself from the instructor dashboard but failed to send. Here is the error I got.

Hello Nilesh,

Thank you for your interest in Open edX.

That exception looks very similar to a bug report from the Fall which was fixed post Aspen (it'll be in the Birch Release). See this for the discussion thread: https://groups.google.com/forum/#!searchin/edx-code/CourseEmailTemplate/edx-code/VhzUeNAUs_8/LTFTHluwSnMJ

Depending on what version you are running (is it a plain Aspen installation?) you might want to try patching your system with the fix that is posted in that above thread.

Best wishes,

Chris Dodge
