Hi All,

I am zipping a file (PGM=ZIP) having header and data in comma seprated format.
i am mailing this file thru PGM=SMTP but i am unable to open the attachment. Warning message i am getting is [WARNING : A/V UNSCANNABLE]

Could anybody help me to resolve this issue?

Thanks,
Amol

What did you tell SMTP are the characteristics of the attachment?

Most likely, the ZIP file is unscannable because it no longer is a ZIP file -- if SMTP treated it as a text file and converted EBCDIC to ASCII the file is totally and completely corrupt.

Robert,

SMTP is a program for mailing (May be client specific). and this the input for mailing job

result,lacs1.zip,binary

I am extremely familiar with SMTP on z/OS -- I've set up multiple SMTP jobs running on different ports on one LPAR, even. In SMTP to send an attachment, particularly a binary file such as a ZIP file, you must (note the mandatory nature) use MIME to tell SMTP how to handle the attachment. I was asking for the MIME statements in your SMTP commands to be posted for review. SMTP is part of the TCP/IP stack installed as part of the z/OS from IBM and there's configuration options that can be client specific, but the actual way it works is not client specific.

Per the RFC specifications for SMTP (which I've read and in some cases have copies of), the general format for an SMTP conversation is:

Fallowing are the messages from the spool.

Let's try one last time.

I did not ask you for details of the spool output. I want to see the actual data you are passing to SMTP. I don't know if your batch job is using IEBGENER or some other utility to write to (B,SMTP) -- or whatever your SMTP writer class is if not B -- but I want to see what the input is to that copy. I suspect that your input is incorrectly specified -- Content-Type should be application/zip (or something similar) not multipart/mixed.

If you cannot provide the SMTP source statements that you are using, I cannot help you since there's not enough data about the problem. In that case, I strongly urge you to contact your site support group for assistance.

Robert,

This is the data after zipping which is passed as an input to SMTP.

Where's the HELO command? Where's the MAIL FROM command? Where's the RCPT TO command? If this is all you're sending, you're not sending SMTP -- SMTP transactions must start with HELO (or EHLO), have a MAIL FROM, have a RCPT TO, and have a DATA statement. You're not showing me any of these.

Your last Content-Type is text/plain -- which absolutely will not work with Zip files (which are binary). Try application/zip or application/octet-stream.
