I have searched high and low all over the internet looking for a tool like this, there are very few and the other ones that exist out there are way too complicated to be worthwhile.
Thanks for making this available. It saved me a bunch of time.
Only issue I have with it is it seems to use PKZip compatibility within the zip file. Removing that dependancy would make it much more easy to manipulate with open source tools.
i was about to write something similar except for one added feature... how hard would it be to expand this tool to include duplication prevention... say for example i want to mirror one server to another, but the old server is still receiving e-mail...
being i am not a C# developer (only vb.net) i cant follow your code 100% and would rather pass something on to you if it can be done...
