Hello Jeremy, I have had this on my TODO, waiting for the next letsencrypt cert update. I dropped the "service exim4 stop ; sleep .2 ; service exim4 start" from my post update script and checked whether exim now automatically saw the new certs. It did. :-) I am not symlinking my certs and since this was on Debian's 4.96-14~bpo11+1 neither of the two symlink-cert fixes are included. (I will consider cherry-picking them anyway.) So it looks like something else was broken at some point in time and is fixed again. cu Andreas -- `What a good friend you are to him, Dr. Maturin.
