3164.0. "How to create the decoder script" by VMSNET::R_HARRIS () Wed Apr 09 1997 08:30

    Hello,
    
    I have a customer who is trying to create is own decoder script. He has
    v2.1 of the SMTP gw. However, he is reading from the v2.o
    documentation.
    
    Two questions. (1) Is the documentation in 2.1 more detailed on how to
    create a decoder script? He is following appendix D-22. It highlighs
    creating a encoder instead of the decoder. Is there more information  
    in v2.1?
    
    Do you create the decoder/encoder in pairs? 
    
    (2) When is the decoder invoked? Is this a manual operation? My
    understanding is that the decoder is used on the recipient end. For
    example, if a binary message file comes in, I must extract and run the 
    decoder to get my raw binary file. I am correct in this assumption? Or
    does the SMTP GW do it automatically?
    
    Thanks in advance for your support.
    
    Regards,
    
    Randy

	1) There is still not much in the manuals in V2.1, just the brefeerence to the (heavily commented) example files. 2) The decoder is activated automatically by the gateway on any SMTP message that is identified not to be MIME. +Mark+

	Re: .1 << The decoder is activated automatically by the gateway on any SMTP message that is identified not to be MIME.>> How do I get the converter to invoke? There is not a Decoder Attribute on the SMTP entity. Do I just replace the decoder files with the new one I create. The documentation is unclear. Thanks in advance for your support. Regards, Randy

	If a file exists with the pathname specified in the docs (mumble/custom_decode) it will automatically be used as the second-best alternative to MIME decoding. The existence of the file triggers its use. +Mark+
3164.4	And the real problem	VMSNET::R_HARRIS		`Thu Apr 10 1997 21:58`	16
	Re: .3 Thank you for your responses. Now, the real problem is unvealed. Mail messages are coming over as UUENCODED messages. He must manually copy the message to disk, and run the DECODER manually. He wants to create a decoder that will DECODE the messages on the fly. Is this possible? The decoders in /var/smtpgw do not seem to be working. Thanks in adavnce for your support. Regards, Randy

	The uuencode etc. scripts present by default in the /var/smtpgw directory are not the ones you are looking for: they are for atypical MIME content-type conversions (well-behaved MIME should be doing base64). The one you want to modify and copy to the location in the manual (preserving a copy of the original, as always) is /var/smtpgw/examples/custom_decode. With this file in the right place, it will be used as the decoder should the first pass by the hardcoded MIME-parsing of the gateway draw a blank. +Mark+
