When sending a file through email on servers such as Gmail etc. they always impose a drastically low file size limit. I really don't understand the reasoning behind this, as file sizes grow.
I am aware of services like Drive, Dropbox, and Apple's 'Mail Drop,' but simply for compatibility, wouldn't it be a better choice for mail hosters to simply raise the limits to those of Drive, because they obviously have the capacity to store large amounts of data, but disable it on email?
I'm sure there's a technical answer due to the SMTP protocol, but any answer would be appreciated!
