posting these attachments as links rather than attachments in CCP4bb messages is the way to go I think. many institutions offer this service (ours does), and there are also free and for-pay online ways to do this (for example www.yousendit.com, but there are many others). Then it is also not a problem to send (sorry, link) even large files. The only disadvantage I can think of is that they expire after some time.
