Mail Service not properly uninstalled creating huge files
Hi, recently I faced a problem that my database was down and I couldnt really start it. I researched all the possible reasons for it until I found that I was using all the 20Gb I have. Then I figured out that the folder /var/mail was taking all the space with two files only.
As I dont use email on my server, I simply deleted one of the files and I dont think its gonna be a problem. At least nothing happened yet.
This problem was caused cos some time ago I tried installing an email application (postfix and similar) and installed some of them. The problem is that I dont really remember which ones Ive installed and which ones I uninstalled. So one of them might be still installed taking allllll the space from my droplet.
My question is: Does anyone know how to list all applications I have installed or know a way to find out which application is creating these huge files (19Gb, yeah) in /var/mail?
I’m totally newbie on linux matters, so I might have done something wrong. :(
Thanks in advance!
