Package: certbot
Version: 0.10.2-1
Severity: normal

Dear Maintainer,

debian provides a group "ssl-cert" (maybe this is part of snakeoil?)
this group should probably have read permission to the certificates 
generated by certbot.

I was installing "prayer" webmail server and it refued to start in TLS
mode using my letsencrypt cert.

This seems to fix it.

 chmod g+x        /etc/letsencrypt/live/ /etc/letsencrypt/archive/
 chown :ssl-cert  /etc/letsencrypt/live/ /etc/letsencrypt/archive/

Read access on those directories is not needed (only execute is needed) 
but denying read is probably not significantly improving security, all
the hidden filenames are easy to guess.
