Maximum incoming email (attachment size) limit

Maximum incoming email (attachment size) limit

I see that the maximum size of received emails can now be set to 20MB, however I'd still like to see it be larger.  It's embarrassing when a client sends me an email with a large attachment and I can't receive it.  50, even 100 MB seems reasonable these days - especially when I'm paying for 10 or 15 GB of storage.

Can this be increased?
