We impose a limit of 5mb for an attachment and up to 50mb in mailbox size. Limits can be lifted if you can give a good business reason. This is quite strict but we also encourage the use of PSTs. Again as mentioned in other posts this leads to some serious archiving, our worst offender currently has around 8Gb of PSTs, the other problem we have is that once a PST goes over 1Gb its stability seems to be effected and can (and often does) just fall over.
