Viktor/Weitse, After spending the last couple evenings looking at options to replace the filter, I have managed to kludge together a working sample in my development environment and it definitely looks more promising than the filter without adding too much complexity to the development process. I was actually surprised to how quickly, given some sample code out there, it was to put in place an smtp proxy. Anyway, just wanted to say thanks for the direction. Gary-
