May I delete exim4 files?

Question

I'm running out of inodes, I discovered that there are ~155000 files in var/spool/exim4/input - may I safely delete those files?

I found out that exim4 is some kind of emailer - but I believe I don't need it.

Answer 1

Almost every *nix host needs a mailer - for system messaging.

You can remove the exim spool files, but it would be much better to investigate what was sent to you. I think those files are messages from cron about some problem(s).

For proper removal you have to enter the /var/spool/exim4/msglog and run:

exim -Mrm <filename>
