Unfortunately, they're not alone. Any number of carpetbagging "anti-spam" companies have materialized, eager to exploit the Internet's collective misery for profit, and willing to engage in wholesale abuse in order to do so. The most common form of observed abuse is C/R, but I've also noted outscatter-by-design, callbacks, and outright spamming. The local blacklist of such entities follows below. As to the snake-oil known as SPF (mentioned elsewhere in this thread), it, like DomainKeys and SenderID, reflects confusion vis a vis the spam problem vs. the forgery problem. Yes, they're related, but solving one is not the same as solving the other -- and at present, the forgery problem is completely unsolvable. (...because any of the 10e8 or so fully-0wned systems out there that can emit apparently-unforged email using any credentials that happen to be present on them...) Efforts should instead be focused on solving the outscatter problem, because doing so helps minimize the impact of the forgery problem. ---Rsk 19948courses.org barracudanetworks.com bluesecurity.com bongosoft.com boxbe.com c-programmer.com collactive.com cruelmail.com ctyme.com emailaccount.com emailaccount.net emailaccounts.com emailsanitizer.com emailservice.com gennux.ca gennux.com hendricom.com hydra.net ihatespam.net junkemailfilter.com junkemailfilter.net junkemailfilter.org limitspam.com mail-block.com mailblocks.com mailfrontier.com mailfrontier.net mindtechuniversity.org netwinsite.com onlymyemail.com rhinosoft.com spamarrest.com spamfighter.com spamsnag.com spamstrike.net ssdcorp.net sunbelt-software.com sunbelt-university.com sunbeltsoftware.com totalblock.net vanquish.com w2knews.com winxpnews.com wservernews.com wxpnews.com zaep.com
