// An example "--filter" script for Windows that verifies the submitting
|
|
// client's IP address. The IP address is read from the envelope file.
|
|
// Invalid IP addresses are rejected by deleting the two message files and
|
|
// exiting with the special exit code of 100. Note that this checks the
|
|
// IP address very late in the submission process; a firewall or DNSBL check
|
|
// might work better.
