Hello, I am being attacked by a lot of spams on my postfix box. What is the best way to block them and fix this for good? It is so bad some of my IPs have been black listed. Thanks for your help. -- Best Regards, Peter R. *** *
MAAWG best practices - please see http://www.maawg.org for several best practice documents. If your IPs are getting blacklisted - they are emitting spam. Please email me offlist and I'll try to help you with some suggestions On Wed, Mar 2, 2011 at 2:16 PM, Peter Rudasingwa <peter.rudasingwa@altechstream.rw> wrote:

Thanks for your help.
1) Hire a professional, as staff or as a contractor, to secure your systems. 2) Find the 'off' switch on the postfix box, and _use_ it.
Get A.S.S.P and integrate it with your postfix box, implement SPF and run dkimproxy on your postfix box and bid spams adieu . You would be surprised the power of ASSP . It is the best out there that kills spam dead on arrival and departure. Sent from my iPhone On Mar 3, 2011, at 10:18, Robert Bonomi <bonomi@mail.r-bonomi.com> wrote:

The headers this guy sent me offlist = what you suggest just wouldn't work, sorry. He most likely had a rootkit on his server that was emitting direct to MX spam. On Fri, Mar 4, 2011 at 2:38 AM, Joshua Klubi <joshua.klubi@gmail.com> wrote:
