Understood, however with RBL's that are of a high level of effectiveness, there are more and more pressures in real world environments to reduce the amount of actual data a server has to process. If as some of the talk in the industry hints at, that there will be legal requirements to track or retain email, then such reductions become more and more paramount. And I do think that your particular setup may be in the minority now, and even more so in the future, so what I am saying is not to DROP RBL's in SA, but not to include certain ones that may be problematic by default. Make it an option to do eg SpamHaus checks, not a default perhaps.. In recent weeks, we have seen the effect of 3 different ISP's whose mail services were affected by SpamHaus blocking their DNS Servers, with accompanying large increases in local processing times and concurrencies. And with the current SA, this is more difficult to turn off via a config option for example.. -- -- "Catch the Magic of Linux..." ------------------------------------------------------------------------ Michael Peddemors - President/CEO - LinuxMagic Products, Services, Support and Development Visit us at http://www.linuxmagic.com ------------------------------------------------------------------------ A Wizard IT Company - For More Info http://www.wizard.ca "LinuxMagic" is a Registered TradeMark of Wizard Tower TechnoServices Ltd. ------------------------------------------------------------------------ 604-589-0037 Beautiful British Columbia, Canada This email and any electronic data contained are confidential and intended solely for the use of the individual or entity to which they are addressed.
