Hi We went for the managed service solution from messagelabs.com which really did a wonderful job in blocking spam using different methods , and in scanning/blocking infected messages that includes scanning against ( viruses, worms, Trojans..etc) Also in case that your entire messaging infrastructure became offline...they can hold the undelivered messages for 7 days as a form of DR.

That way, no single keyword or blocking list will cause a message to be "blocked". These products also offer you features like a quarantine (so a user can retrieve a message that was blocked if it shouldn't have), anti-virus, content filtering, and auto-encrypted email (e.g., for HIPAA compliance). I'm afraid that blocking messages due to the listing in a single block list service is going to yield poor results (plenty of false positives and false negatives). http://www.espionintl.com http://www.barracudanetworks.com http://www.ciphertrust.com/products/ironmail/ Seth Robertson IT Security Forensics Specialist -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of mbs Sent: Thursday, January 04, 2007 3:23 PM To: security-basics () securityfocus com Subject: Re: SORBS I am considering setting up our Exchange servers to use some sort of SPAM blocking list service. SORBS sounds like the wrong choice. Are there any better options, or should I just learn to love deleting SPAM? Michael Dan Tesch wrote:
That organization is un-believable, good luck! I spent at least 40 hours over the course of a month or two trying to get a domain off their list. Seemed like every time I passed one of their criteria, there was something else wrong. It came down to the fact that the server IP was in a block of SBC addresses that they didn't like how they were configured. -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of policysup () gmail com Sent: Tuesday, January 02, 2007 2:20 PM To: security-basics () securityfocus com Subject: SORBS In trying to get de-listed from SORBS I get: " the someone is lying, pay the fine response." A friend once said: " Life is so much easier when you assume that anyone who disagrees with you is evil. Cuts down on the need to take responsibility or do any real objective thinking.
