Delete specific attachment file through Conversion Channel ?

Question

version : iMS5.2 sp1
O/S : Solaris 2.6 Generic_105181-29
I wanted to delete specific attachment file(ex: ALTDESK.ZIP) through Conversion Channel.
So I set up like below..
1) In mappings file
=================
CONVERSIONS
IN-CHAN=tcp_intranet;OUT-CHAN=tcp_local;CONVERT Yes
==============
I only want to delete attached file from tcp_intranet to tcp_local.
2) msg-INSTANCE/imta/config/conversions
example mail header ::
--- omit ----
MIME-version: 1.0

- conversions file setting
==================================================
in-channel=tcp_intranet; out-channel=tcp_local;
in-type=application; in-subtype=x-zip-compressed;
parameter-symbol-0=ALTDESK.ZIP; parameter-copy-0=*;
dparameter-symbol-0=ALTDESK.ZIP; dparameter-copy-0=*;
message-header-file=2; original-header-file=1;
override-header-file=1; override-option-file=1;
command="/product/leeky/convert.sh"
============================================
3) /product/leeky/convert.sh file
========================
#!/bin/sh
if [ $? -eq 1 ]; then
echo "STATUS=178030178" >> $OUTPUT_OPTIONS
else
cp $INPUT_FILE $OUTPUT_FILE
fi
=========================
4) The problems I face are
- All of zip files which are filtered is deleted. As you can see 2) I only want to delete ALTDESK.ZIP file
But, all of the zip-compressed files are deleted at the moment.
- This converison channel is work(even if all zip-compressed files are deleted). But sometimes this is not
working(2 or 3 times out of 10). I don not know why.
- Above all, I am not sure 2) and 3) settings are good. English is a second language to me. So it was
not easy to understand conversion channel setting in Admin Guide.
- How can I see the out put of "$OUTPUT_OPTIONS" ? I do not know where I can see that.
Is there anybody to help me ?

Answer 1

The section of the admin guide which can help is:
http://docs.sun.com/source/816-6009-10/channel2.htm#42283
Here there is an explanation of how the mime headers of the message part would align with the entries one would put into the conversions file entry. (The document has an error where it talks about APPARENT_NAME and APPARENT_FILENAME. It should really say the words "NAME" and "FILENAME" respectively).
Based on that document, the MIME headers of your message part :
Content-Type: application/x-zip-compressed
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=ALTDESK.ZIP
will align with a conversions file settiong of:
in-channel=tcp_intranet; out-channel=tcp_local;
in-type=application; in-subtype=x-zip-compressed;
parameter-symbol-0=NAME; parameter-copy-0=*;
dparameter-symbol-0=FILENAME; dparameter-copy-0=*;
message-header-file=2; original-header-file=1;
override-header-file=1; override-option-file=1;
command="/product/leeky/convert.sh"
and a /product/leeky/convert.sh script which reads something like:
#!/bin/sh
grep "$FILENAME" /product/leek/badfiles.list
if [ $? -eq 1 ]; then
echo "STATUS=178030178" >> $OUTPUT_OPTIONS
else
grep "$NAME" /product/leek/badfiles.list
if [ $? -eq 1 ]; then
echo "STATUS=178030178" >> $OUTPUT_OPTIONS
else
cp $INPUT_FILE $OUTPUT_FILE
fi
fi
The lines:
parameter-symbol-0=NAME; parameter-copy-0=*;
dparameter-symbol-0=FILENAME; dparameter-copy-0=*;
tells the conversion channel to make the environment variable $NAME avaliable to your program with a value corresponding to the "name=" clause on the Content-Type line of the MIME headers. The environment variable $FILENAME is made avalable to your program and takes on the value extracted from the filename=" clause on the content-disposition line of the MIME headers.
The document at :
http://docs.sun.com/source/816-6092-10/conversion.html
may help provide other examples.
