Does anybody here know anything about the legitimacy of Constant Contact <http://www.constantcontact.com/anti_spam.jsp> ? In preparing a list of HOSTKARMA_W violators for Marc, I noticed a very large amount of spam, coming from completely different companies, was sent through constantcontact.com servers using their "Safe Unsubscribe" feature. After some web searches, I decided to use the unsubscribe feature, but apparently I needed to unsubscribe every email address with every company that uses constantcontact.com. To me, this means it is quite clear that Constant Contact's anti-spam policy is improperly enforced at best and flagrantly ignored at worst. The biggest problem is that they're well seeded in the DNS whitelists, including HostKarma and IADB, and they often use SPF, which gets the "OK" from my double-check in khop-bl. Before I write a custom rule to add points to anything passing through a constantcontact.com relay, I was wondering if anybody here had thoughts on this. (Note, questionable custom rules like this get tested on my production servers with near-zero scores, then real scores, and /then/ they find their way to my sa-update channels.)
I wouldn't say they are perfect but they try to be. It's close enough for my white list. They shut down abusers and the opt out works.
