I would agree on a size limit though.
The kind of size limit required to keep attachments small enough to not annoy people who are not interested in them would be too low for this purpose. The annoyance increases further when people with broken email clients (or who just never bothered to learn their tools) include senders' attachments in their replies. A typical digicam or scanner produces multi-megabyte files. Reducing them in size to fit within e.g. a 1MB limit would still cause the same level of inconvenience to the sender as uploading it somewhere and posting a link as well as reducing the quality and utility to those who are interested. I also note an inverse relationship between the size of an email and the quality of its contents. Further, an orders-of-magnitude explosion in the resources used by this list would reduce the number of people willing to host it. My shell server which I use for mail is perhaps typical: it has a 20TB/month transfer cap which is effectively infinite, but its 20GB disk would be eventually consumed by all of those attachments kept forever in the list archives that people also want.
