Qmail Backscatter Solution Required

I am running a open source control panel called kloxo I need a solution configured and configured for my server and then donated to <[login to view URL]> please. AS alternative what in long run would be better is to get rid of Qmail and integrate postfix I am not sure of cost but if anyone would like to comment your more than welcome ========================================================== users email is being blocked thanks to [login to view URL] I need help with qmail server and a solution integrated and configured. This is causing emails to bounce from various servers,I got calls from clients and went to <[login to view URL]> entered in [login to view URL] saw a blacklisting I clicked and was brought to <[login to view URL]> AND GOT BELOW Testresult for [login to view URL]: This IP IS CURRENTLY LISTED in our Database. Please note that this listing does not mean you are a spammer, it means your mailsystem is either poorly configured or it is using abusive techniques. This kind of abuse is known as BACKSCATTER (Misdirected Bounces or Misdirected Autoresponders or Sender Callouts). Click the links above to get clue how and why to stop that kind of abuse. =========================== SEE THIS FORUM =========================== <[login to view URL]> Did some research <[login to view URL]> Backscatter (also known as outscatter, misdirected bounces, blowback or collateral spam) is incorrect automated bounce messages sent by mail servers, typically as a side effect of incoming spam. in the [login to view URL] it states the reasons for it and cures, but does anyone have qmail knowledge to have this as partof config as I may not be alarmist if the Qmail setings are incorrect to have caused this issue?? =================================================================== also found this for Qmail <[login to view URL]> Hope kloxo coders will look into this also please QUOTE: What is the best solution to avoid backscatter? What's about BATV <[login to view URL]>? The qmail all in one (aio) patch supports BATV <[login to view URL]>. QUOTE: What is the best solution to avoid backscatter (stop doing)? If you're willing to do some relatively complex software installation, Bruce Guenter's mailfront package can do a range of checks at SMTP time and reject rather than bounce most undeliverable mail. You also have to install his CVM package which provides a daemon that mailfront can use validate addresses handled by qmail or vmailmgr. The documention is sparse but adequate, and it's very well written. I use mailfront to do invalid address rejection along with some other built-in rules, and have added modules to do DCC checks and call spamassasin's spamd at SMTP time. [login to view URL]
