Im a huge fan of gmail
But i have noticed one small flaw with it; it doesn’t always detect attachments.
Of course this isnt a hugh issue, you can simply search for has:attachment in the search bar. but this is a bit annoying so last week i spent a short amount of time creating a set of filters to tell not only tell me if there is an attachment but if that also what type of attachment it is.
This is what is displayed
gmail-filters
You’ll have to enable the inport filter lab to get it to work (it might take a while though).
