What size limit are you imposing on individual messages? UofM imposes a
limit of 100 MB for a single SMTP mesage, which, taking MIME encoding
losses into account means that users can generally send a message with
at largest a single 67 MB attachment.
Do you have duplicate delivery suppression enabled on your IMAP server?
If people are forwarding large emails to other users in-house, duplicate
delivery suppression can potentially save a lot of storage space.
Have you educated users about other ways to transfer large amounts of
data? For example, dropbox-like services? SFTP to personal home
directory space? There are a variety of cloud-based and in-house
options. When educating users, be sure to emphasize the benefits of
non-email-based methods -- including faster speeds (potentially), much
better security, and more features.
