Most admins know that a 9.9 MB file gets expanded by 4/3 factor so it will 
not fit into a 10 MB message size limit.

But I keep running into people who are not aware that email results in a 
33% overhead on each (binary) file.
Hmm.. that may be the problem then. So instead of putting 10M I really should be putting 9.5M or 9M?


How would you spend $50,000 to create a more sustainable environment in Australia?  Go to Yahoo!7 Answers and share your idea.
