qmail-spp - problem when setting env var

[Derek S. <de...@in...>]

The filters are all running as bash scripts

I have the following code in the "helo" filter:

if [ `env | grep ^RELAYCLIENT` ]; then
   echo "$NOW HELO+$TCPREMOTEIP, LOCAL set to Y by RELAYCLIENT" >> $LOGFILE
   export LOCAL='Y'
   echo "SLOCAL=Y"
fi


Then in the "mail" filter I have:

# set flag for internal mail - kludge because qmail-spp does not seem to 
set env vars properly
if [ -n "$LOCAL" ]; then
   internal='Y'
fi
#internal=$LOCAL
echo "$NOW FROM+$TCPREMOTEIP, LOCAL:$LOCAL" >>$LOGFILE


I get the following in the LOGFILE:
20040921080755 HELO+xxx.xxx.xxx.xxx, LOCAL set to Y by RELAYCLIENT
20040921080755 FROM+xxx.xxx.xxx.xxx, LOCAL:Y
Z


Can anyone explain why I get an apparent value in $LOCAL of "Y\nZ" ?

TIA,
Derek
