Botnets

Terry Zink has been posting articles about botnets as traced by Hotmail. I do not often talk about botnets as they are outside my area of expertise. They are not something I deal with, as no one who uses botnets is welcome as a client here.
My clients and I, however, do have to deal with the fallout from botnets.  Because of botnets, receiver ISPs are extremely suspicious of mail from any IP address that they have not seen mail from previously. Mail from new IPs is, more often than not, a newly infected Windows machine. This results in mail from new IPs not starting with a reputation of zero but starting with a negative reputation.
Botnets are another example of spammers making it more difficult for mailers with permission to use email.

Venkat posts today about the ruling in the Asis v. Azoogle case. I have not yet had a chance to read the whole ruling, but in talking with Mickey over at SpamSuite it seems to expand the Gordon ruling a bit.
Mickey posts on Intellectual Intercourse about spam received from a recruiting agency trying to get him to hire one of their clients. This spam was amusing in that it contained reference to a bill that Mickey helped defeat years ago.
Box of Meat blog links to a CSO online article graphically demonstrating a botnet. The representation is really helps to understand the scope of the problem.
On Bronto Blog DJ posts about resurrecting old addresses. He has it right when he says: “If you continue to send email to customers that is random and unexpected, there will be consequences.”
Matt at ReturnPath has a couple posts about who should get delivery services and how ReturnPath chooses customers. This is something I end up dealing with occasionally. There are not specific types of companies I refuse to do consulting for. I will generally provide consulting on best practices to any business segment. My one restriction is that I will not provide ISP relations (ie, contacting the ISPs) for companies that do not send opt-in email. This has caused consternation with some potential customers.
Mark Brownlow at No Man is an iland suggests renaming “open rate” as “render rate” in an effort to make it much clearer what “open rates” really measure. Expect to see render rates referred to here on this blog in the future.
Josh talks about suppression list abuse on Deliverability.com. For those of us who use unique addresses for every signup, it quickly becomes clear that there are leaks in the suppression process. I have also seen problems with leaks from subscriptions, so do not think the problem is just in suppressions.
