I am looking to have both a smarthost and incoming mail from the same provider. I am running Exchange 2007 on SBS 2008. I keep looking and am not having much luck finding someone who can do both. I want to reduce complexity and number of vendors I have to deal with. In the end I might be looking in the wrong place or asking the wrong question.
Currently I use authsmtp as the SMTP service, and roaring penguin as the incoming/anti-spam/av service.
Any help is appreciated
