Weird log entries

In my auth.log I'm getting these entries:

Code: 
exim4: gethostby*.getanswer: asked for "Hostname.Home IN AAAA", got type "A"

But I'm not a server and I'm sure I'm not running any file sharing or mysql or anything like that :/ I'm wondering if it's my router or someone is trying to connect to my computer or something.

Also, why do I have a lot of ssh key rings in my .cache directory ? I shouldn't have that many as I don't use ssh but I think someone is trying to connect remotely to my machine.
 
I'm not claiming expertise on this, but.
(1) My machine actually does run apache and mysql and running cd /var/logs && grep exim4 doesn't return a single for me. Could you run in terminal the command whereis exim4 and which exim4 and post the output here?
(2) When I run cat ~/.ssh/known_hosts only about 10 lines are returned. I do use ssh though, and that corresponds roughly to the number of different hosts I have connected to. You might want to clean this cached list - you could edit the known_hosts and remove all entries.

the first command outputs this

Code: 
exim4: /usr/sbin/exim4 /etc/exim4 /usr/lib/exim4 /usr/share/man/man8/exim4.8.gz

and the second one doesn't output anything at all, as for the known ssh host list. it doesn't appear to exist neither.

1. Do you need the Exim Internet Mailer? If not, you can run sudo apt-get purge exim4 if you're running Debian/Ubuntu.
2. Can you check to see if the .ssh directory even exists: ls -la ~/.ssh
