Not knowing much about mail protocols, the way I think about solving attachments (and decoupling it from db) is as following. The approach is mostly geared towards web-mail services and is most likely outside the scope of a typical email server. Today's email is mostly web based and mail servers should be providing a solution for it.

1. DB to never store attachments, this is just not efficient and there are many articles out there on this topic.

huh. I decided to use aox rather than any number of simpler and easier to deploy solutions simply because backup is a consistent point in time, and having attachments integrated is central to that. Whether a memcached or equivalent could be used by the mail store for hot data is another matter.
