Exim4-light-daemon

I got the (not so) brilliant idea to upgrade MySQL to 5.6
After that my exim4 installation is fubar.
I've tried a number of things to solve it, and even the apt-get install vesta is giving me the same error as this below:

apt-get install vesta
Reading package lists... Done

vesta is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

After this operation, 0 B of additional disk space will be used.

Setting up exim4-daemon-light (4.80-7+deb7u1) ...
Starting exim4 (via systemctl): exim4.serviceJob failed. See system journal and 'systemctl status' for details.
failed!
invoke-rc.d: initscript exim4, action "start" failed.
dpkg: error processing exim4-daemon-light (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
exim4-daemon-light
E: Sub-process /usr/bin/dpkg returned an error code (1)

Im clueless what to do, i didnt think the MySQL-upgrade would cause this mayhem :)
Thanks in advance.

Well i figured it out, when i removed mysql 5.5 and installed 5.6 i some how got the exim4-daemon-light package instead of the heavy one.
Forced a removal of the package exim4-daemon-light and re-installed the exim4-heavy package, then i had to reboot the machine for everything to be in sync again, cause starting only the exim4-daemon wasn't enough for receive email, only send.
But everything is running now (i think..) haven't had time to check the VPS-domains, but surely they will complain if they not can send emails..

Lesson learned, but i need MySQL @ 5.6 for the InnoDB full text search to work.
