Windows Server 2008 IIS SMTP Support


DONE Windows Server 2008 IIS SMTP Support

| Last activity: 9 years ago
ORF currently does not work with the Internet Information Services (IIS) SMTP Service on Windows Server 2008. Add support to the above platform, like in the case of Windows 2000/2003.


It should be noted that support for the above platform is not entirely up to us: the IIS6 SMTP Service under Windows Server 2008 is broken many ways. If we receive significant interest in this request, we will start working with Microsoft to fix the problems that led to our decision of not supporting IIS SMTP on Windows Server 2008, only Exchange 2007.

This feature is the main reason we currently use this product. We currently use IIS 6 as a smarthost to route incoming and outgoing email. Using ORF has simplified our SPAM and Virus fight and doesn't require any additional Exchange licenses. I'm really surprised more people don't use IIS as a smarthost, since the golden rule is you should never directly forward SMTP traffic to your exchange server... all email should be prefiltered, then routed reducing the workload of the exchange server.

Either support IIS on Windows 2008 or use an own smtp proxy, so that the use of Windows 2008 doesn't mean to have an Edge installed. Which by the way negates the "golden rule" above. ;)

ORF has been one of the most solid software products we have ever used and we think it's imperative that Vamsoft find a way to support ORF with Windows 2008 to maintain it's viability and ensure future sales of ORF. We can't stay at Windows 2003 level for many more years.

ORF is a rock solid product that has helped alot on my 3 gateway servers, With the intro of Windows Server 2008, a lot of unexpected changes came with regards to SMTP service. While I currently do indeed have ORF running on 2 Windows Server 2008 boxes, it is not without problems and was a pain to get up and running. We need this to work, although even better is if ORF had its own SMTP engine so that then it could be used without IIS on a gateway server.

Would really like to see you guys extend support to Win 2008...

We're using ORF on Windows 2008 SP2 (x86) without any issues... Kind'a weird since I read now this isn't supported. Why is that the case?
by Jeroen 9 years ago
@Jeroen: In short, Windows 2008 is supported, but only with Exchange 2007 (or 2010) installed on it. Without Exchange, only with IIS SMTP, it is not supported. I presume you have Exchange 2007/2010 installed, haven't you?
by Krisztian Fekete (Vamsoft) 9 years ago
New customers whithout Exchange are not able to use (and buy) your software; all exisiting customers will run out of support in 2010. Of course, the correct Request is Windows 2008 R2

I strongly second the suggestion above to either support this SMTP mode of ORF in either Windows 2008 or better yet, include your own SMTP engine.

You can't expect your customers to stay on W2003 perpetually?
by Andy 9 years ago
@Andy: Of course not. Most of our customers are already using Windows 2008 and R2 with Exchange 2007/2010 :) But seriously: as Peter mentioned in the first comment, it was not entirely up to us. Apparently, Microsoft considers the IIS SMTP Service a legacy component: it is installed as a part of IIS 6 (the native package of Windows Server 2008 is IIS 7) and the fact that it was not updated for IIS 7 suggests that it is getting at least de-emphasized. What sends an even stronger message is that the SMTP Service under Windows Server 2008 was broken many ways, including the programming interfaces (that ORF relies on, see, the administration interface ( and even logging ( Shipping ORF to a platform so unreliable would have been call for trouble. So to answer your question: it was not us who expected IIS SMTP users to stay on Windows 2003, it was Microsoft apparently... Fortunately, Microsoft fixed some of the bugs which prevented ORF from working, and for the rest we found workarounds, so the next interim version (released within two weeks) will support IIS on Windows 2008 (not only Exchange 2007 and 2010).
