I just posted a feature request for incoming emails. If this should not be possible, I´d like to hear your advise for the following challenge...

I like to work with mindmaps; I draw them on my office PC and on my smartphone. Unfortunately, my office PC is not allowed to access dropbox, so I need another way to send documents to my smartphone. My idea was to send these files (for instance MyMap.mm) to my smartphone as an email attachment. Then, on the mail´s arrival, a task should save all *.mm files to sd card automatically.
Do you have any hint on how to solve this with Automagic - any workarounds to my "incoming email trigger" feature request?
Regards,
Jost
