What does this patch do that chkuser doesn't already do?
It stops delivery of non existant adresses at the earliest possible point.
Here is what my server does:
# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 s1.digitale-wertschoepfung.de ESMTP
EHLO testing
250-s1.digitale-wertschoepfung.de
250-STARTTLS
250-PIPELINING
250-8BITMIME
250-SIZE 0
250 AUTH LOGIN PLAIN CRAM-MD5
AUTH PLAIN ...
235 ok, go ahead (#2.0.0)
MAIL FROM: <[EMAIL PROTECTED]>
250 ok
RCPT TO: <[EMAIL PROTECTED]>
250 ok
Now compare that to this:
(i copy and pasted this from the aforementioned site)
% telnet a.mx.jms1.net 25
Trying 209.114.200.128...
Connected to a.mx.jms1.net.

Can chkuser do this?
