I believe Raymond's response was addressing the fact a server
connection could possibly be interrupted before it had a chance to
issue the SMTP QUIT command. I would think being listed for that alone
would be ridiculous.
if its this i would agree, cant exim see diff in not sending quit or
drop connection ?
It can. This is exactly what makes the "noquit" list possible.
Exim has two relevant ACLs. One that is run when the connection is
closed after a QUIT, and one that is run when the connection is closed
without a QUIT. So one of those two is run at the end of every
connection, depending on how it ended.
As I understand it, Marc has added some configuration to his system so
that when the "Closed without QUIT" ACL is run, he adds the IP address
to a queryable list.
It is described here:
http://wiki.junkemailfilter.com/index.php/Spam_DNS_Lists#Tracking_use_of_QUIT
It is described as "Experimental"
His list gives three responses:
* 127.0.1.1 - QUIT is used
* 127.0.1.2 - No QUIT is used
* 127.0.1.3 - Mixed - Quit is used sometimes
If you don't want the "Closed without QUIT" part of the list, there's
nothing stopping you from using every other feature of his lists without
using this particulary part. You wouldn't use a DNSBL without knowing
how it works first would you?
When I say, "you," I'm refering to the people using the JMF lists, not
specifically you Benny.
