I use IMGate instead of iMail's IP filters. Just did a quick check and found that my IP-based filter file has 13,222 lines in it -- almost all for rejecting email, just a few for white listing a specific IP.
I also host email for a company based in the US that has offices in China, Taiwan, Australia, Italy, and Germany. They love the filters and while there is an occasional problem, it's always with a new account in China that has chosen to use a prolific spam host as their ISP. They are directed to choose another provider, which they do, and that's that. The bottom line is that much of the IP space has no business sending email, and blocking can be a valid decision in the face of the staggering amount of garbage being sent -- to say nothing of the growing increase in criminal fraud (e.g., phishing).

While our clients are usually unable to use such tactics, your condescension takes the point much too far. There are many, many small and/or regional businesses within the US for whom it is not at all "absurd" to block mail from certain country-based IP ranges. I won't even try to give you examples from my own experience -- there are too many to even begin. > And don't expect to do ANY business. . . Come on. Any business, or business consultant, who chooses to use this class of tactics will first take note of the current and prospective geographic borders of the company. Newsflash: not everyone cares about your "emerging markets." It's pretty clear that you've never worked for an intrastate careers site, a local real estate company, etc. In all, the only vertical that could _never_ use such DNSBLs for single-test rejection is an ISP, due to the naturally wild nature of their subscribers' correspondents. (Even in that sector, there are regions of the US in which wholesale blocking by country would likely be embraced by the overwhelming majority of subscribers, but that touches on cultural issues and is difficult to imagine declared in a EULA.) You'd evidently be very surprised at the tests that are used to great success by large and growing businesses and their advisors. I've always been a strong opponent of using these tests without full requirements gathering, but claiming that only "family" servers can ever use them is divorced from reality. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/rel ease/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/dow nload/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/downloa d/release/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
