I'm running a Centos 7 system and I have just done a 'yum update' for the first time in a while.
One of the effects of this was that my exim died. To finish off the update I rebotted the server. Exim did not restart. Checking the status I got the following: root@ollie2 ~]# systemctl status exim ● exim.service - Exim Mail Transport Agent Loaded: loaded (/usr/lib/systemd/system/exim.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Tue 2017-05-02 09:56:57 BST; 4s ago Process: 14002 ExecStart=/usr/sbin/exim -bd -q${QUEUE} (code=exited, status=1/FAILURE) Process: 13998 ExecStartPre=/usr/libexec/exim-gen-cert (code=exited, status=0/SUCCESS) Main PID: 14002 (code=exited, status=1/FAILURE) May 02 09:56:57 ollie2.ringways.co.uk systemd[1]: Starting Exim Mail Transport Agent...

[root@ollie2 ~]# The offending code was in acl_check_data and was: # GPS added 2014-04-30 warn message = X-MIME-Error: $demime_reason demime = * condition = ${if >{$demime_errorlevel}{0}{1}{0}} set acl_m_greylistreasons = Message has MIME error: \ $demime_reason\n$acl_m_greylistreasons As you can see, this code has been in for a long time. Can anyone tell me why a system update would break this, and what I need to do to fix it. All of the Google responses that seem to relate to this all date back to 2005 -> 2008 so I don't think they're relevant.
