hmm, not exactly representative for IMGate.
After you accept that a certain amount of merde is ALWAYS going to get
through (so you don't repeatedly waste hours trying to block that tiny
%age), and that there will always be false positives (easily and quickly
whitelisted), you can mostly "fire and forget" with IMGate's anti-abuse
gateway.
here's an IMail IPS in LA with a 50% reject rate and no complaints:
Grand Totals
------------
messages
4868 received
4853 delivered
32 forwarded
38 deferred (232 deferrals)
77 bounced
2429 rejected
and the rejects break-out:
2 RBL dynablock.wirehub.net
4 ACL header checks
4 SMTP invalid [EMAIL PROTECTED]
11 Other
12 RBL relays.visi.com
13 ACL unauthorized relay
14 ACL body checks
35 RBL orbs.dorkslayers.com
37 ACL [EMAIL PROTECTED]
48 SMTP unauthorized pipelining
53 DNS no A/MX for @recipient.domain
57 RBL blackholes.wirehub.net
72 RBL proxies.relays.monkeys.com
116 DNS nxdomain for MTA PTR hostname
124 RBL relays.ordb.org
305 ACL unknown local user
400 ACL [EMAIL PROTECTED]
489 DNS timeout for MTA PTR hostname
646 DNS no A/MX for @sender.domain
2442 TOTAL
And this particular IMGate user is not using a lot of RBL checks, and the
ones he does use, as you can see above, don't contribute a huge %age to his
rejects.
