>From what I am reading, the change is based in the fact that Event Sinks have been replaced by Transport Agents, and that Exchange 2007 no longer depends on IIS. smtpreg.vbs allowed you to touch the IIS SMTP Service and add rules to it (allowing VBScript or EXEs to intervene prior to message delivery). Exchange 2007, no longer relies on IIS, and therefore smtpreg.vbs won't help you hook into the IIS SMTP server anymore (because it is now a proprierary SMTP engine). If you can find a comparable way to hook into the "Transport Agents", you should be able to use Chris Lewis' ESA or any other old-style event sink (but with some modification). The short answer is that they have .NETified Exchange 2000/2003 "Event Sinks" into 2007 "Transport Agents". Sorry I don't have more info. I've not kept up on current versions of Exchange since my current employer does not require me to admin Exchange systems.
P.S. If my research is flawed, and someone knows a solution, please share it. HTH, Steven ________________________________ From: Donald F. Caruana [mailto:[EMAIL PROTECTED] Sent: Saturday, November 24, 2007 7:18 PM To: users@spamassassin.apache.org Subject: SpamAssassin on Exchange 2007 I was happily humming along with Spamassassin on Win2k3 with Exchange 2003 for some time now (yes, you can do it all on one box). I was using Chris Lewis' ESA sink which worked great. However, after an upgrade to Exchange 2007, I've come to realize that the old smtp sinks have been deprecated and the ESA install just flat out fails (the smtpreg.vbs script that Microsoft made available previously actually fails), leaving me in a lurch for a spam solution. Does anyone know if there has been any success in getting this configuration to work with Exchange 2007? Getting SA to work wasn't issue, but the link, ie ESA is the trick that's got me getting bombarded with spam. Any help would be greatly appreciated. Thanks, Don
