If that "SMTP client" is in mynetworks/relay_for_addresses, it's obviously trusted for any number of connections. not even under consideration.If you're saying that a hosting client (obviously, this was what the post in question was referring to in using the word "client": http://www.i360hosting.com) with 100+ users is never going to hit your server 100 times an hour from the same IP, you've never run a hosting company.
I made my point, which is perfectly correct and valid which had nothing to do with SMTP client connections from mynetworks, but from random MTA's on Internet to an any MX host.I'm sure you've misunderstood the issue, since surely you wouldn't make such a mistake if you had all the variables in hand.
ok, drop simultaneous if you want, and I also said per-period, to remove that qualification completely.Nobody said anything about simultaneous connections (except you)
merely the likelihood of legit NAT clients being interpreted as a concentrated attack over an period of time designed to catch baddies.
legit clients behind NAT send to MX's or send to an SMTP gateway??
Assuming the NAT is many-clients-to-one-public ip, all the
this is essentially a non-issue, but your conclusion is absolutely wrong for a hosted environment.
no, it's not.
ok, prove it. show me where these clients-behind-NAT are sending to random internet MX's and making over 100 connections/hour or per day to any one of them.Grepping just proves this point.
