mail_filter plugin: failed: EOF without input (Gedalya)

Sat Feb 8 13:29:07 EET 2020

I just modified mail-filter-out.sh like this:
cat  mail-filter-out.sh
  #!/bin/sh

  USER=$1
  cat > /tmp/tempfile
  cat /tmp/tempfile

cat  /tmp/tempfile

Hi,

Your scripts are reading all the available input and not producing any output. This way the email message is lost.

You could add the line:

cat tempfile

or just replace "cat > tempfile" with "tee > tempfile"
