Please fill out the fields below so we can help you better. My domain is: test.ertos.nicta.com.au I ran this command: ./cerbot-auto It produced this output: Traceback (most recent call last): File “/usr/lib/python2.7/dist-packages/virtualenv.py”, line 2283, in main() File “/usr/lib/python2.…

This is to authenticate EXIM when it talks TLS, Not S/MIME.

Great! I misunderstood what you mean by “for Email”. @bmw , any idea what might cause this error in certbot-auto?

@wom-bat , can you rerun certbot-auto with the --verbose command line option and post the full output?

–verbose pinpointed the problem: /tmp was running out of space. I reran with TMPDIR=/var/tmp and it got to completion. Thanks for all the help!

Just to be clear, Let's Encrypt can't issue S/MIME certificates for use with e-mail accounts.
