Description of problem:
Package exim-clamav contains in postinstall scriptlet the following line:

/bin/mkdir -p 0750 /var/run/clamd.exim

This creates the directories 0750 (in /, because the working directory is /) and /var/run/clamd.exim .

But I assume there is a syntax error in this command call. I assume "0750" should not be a new directory, but should be interpreted as the file mode of directory /var/run/clamd.exim. There must be a "-m " inserted before "0750". See "man mkdir":

       -m, --mode=MODE
              set file mode (as in chmod), not a=rwx - umask

       -p, --parents
              no error if existing, make parent directories as needed


Version-Release number of selected component (if applicable):
exim-clamav-4.87-5.fc25.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install a Fedora system without package exim-clamav installed.
2. ls -l /
3. dnf install -y exim-clamav
4. ls -l /

Actual results:
Directory /0750 exists at step 4.

Expected results:
Directory /0750 does not exist at step 4.

Additional info:
I found directory /0750 since many Fedora versions, so this error exists a long time. But I haven't previously found the package that has created this directory.
