I have a dedicated server that doesn't need to use email on any account, and I found that the disk is getting full often. I use to fix it removing domlogs and some apache logs but now that didn't solved it so I searched what was using the most space on disk and found that the folders
/home/user/mail/new/ is full of files, I removed those folders from a few users and now the disk is not full anymore.
How can I disable email capabilities so those folders wont get full of files anymore?
The server doesn't even have an email address configured on any account so I assume it's all spam from some catch-all address.
