I wanted to follow up to my previous email with a few more useful details I neglected to mention previously: I'm running on Debian: Linux hostname 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2 (2016-04-08) x86_64 GNU/Linux With this version of exim: Exim version 4.84_2 #2 built 13-Mar-2016 17:47:19 logrotate is version 3.8.7, but as I mention the problem persists if I use exicyclog.
