Thanks,
Miguel. That solves the mystery of Verify Client. Since we are not allowed
to receive mail, our problem (flooding a firewall with disconnected packets) is
not likely to be solved with that exit. Originally, we were told that it was
e-mail. Today, we got firewall monitors to check the message meaning, and
the word from Cisco that it is a generic "packet that has no
specific connection in the firewall unit's connection table", not
specifically e-mail.
This appears
to be a monthly occurrence, but there is no pattern connecting it with a day of
month, day of week, or time of day. Not being a TCPIP guy, I am now stumped as
to what we can do. Any suggestions.
Regards,
Richard Schuh

Richard,
From the z/VM TCP/IP Programmer's Reference:
Note: The client verification exit is called for each HELO or EHLO command processed for each mail item received from the network. Client verification is not performed for mail items received from the SMTP virtual reader.
How are you sending the mail, and from where? Something like "sendfile test test a [EMAIL PROTECTED] (smtp" will not result in the exit being called. If you add TRACE DEBUG to your SMTP CONFIG file you will see the following message on your SMTP console when a HELO or EHLO command is processed:
#<N> Client verification results: <data>
Where <N> is the connection number and <data> is a string describing the results. In my example (and I imagine in your case) <data> is "Batch". If the exit was executed, the value would be something else ("Success", "Failed" etc.).
