Hi all,

Finally, I've been able to configure outgoing mail on common-lisp.net using TLS on outbound connections. As it turns out, I had to resort to ACLs (setfacl/getfacl) to assign Exim's primary group (Debian-exim) read access to /etc/letsencrypt/{live,archive}. For some reason, being granted read access through the secondary group, doesn't work for Exim and leads to "Error reading file" messages in the logs.

On my test messages, GMail now reports that common-lisp.net used encryption to send the mails.)

(Consider this mail to be a test-case for mails sent through the mailing list software.)

Regards,
