Install or Not

[Nick Thompson]

I am trying to (re) install MailScanner 4.26-1 on a Raq4, after deleting
it because my version of sendmail was not up to date.

Although I have deleted all the MailScanner files I can find, when I run
install.sh I get a message:

package mailscanner 4.26-1 is already installed.

Is there any way I can force the installation, or where is it finding the
reference saying it's already installed ?

Thanks in advance
