HTML disarming died, status = 13

[Shawn Iverson]

Ferry,

I am having trouble reproducing the issue on my end. I am still looking 
into this. This is looking more like a failure to spawn the child 
process and pipe the results back to the parent process.

Error 13 on a pipe is "Permission Denied." This can be caused for a 
variety of reasons. Filesystem permissions, mandatory access control 
issues (i.e. SELinux or Apparmor), and kernel level issues such as 
hitting an upper limit that is set too low or a kernel bug.

What do you currently have for this setting in MailScanner?

"Ignore Denial Of Service"
