mail_filter plugin: failed: EOF without input (Gedalya)

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


&nbsp; USER=$1
&nbsp; cat &gt; /tmp/tempfile
&nbsp; cat /tmp/tempfile



cat &nbsp;/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 &gt; tempfile" with "tee &gt;
tempfile"
