25 megabytes where I last was... The main issue with permitting large
attachment sizes was not really network issues, this could usually cope
when given time to clear backlogs. Where we ran into issues was in getting
users to not use email as file storage. It was hideously inefficient to
store files in there, made the backups enormous (we didn't have any good
deduplication in place), and provoked endless helpdesk cases along the
lines of "my inbox is full, why?" and "can I have more inbox space?". Use
your imagination to fill in the blanks with the appropriate amount of user
angst (I'm really important, I need this yesterday, etc) and you get the

Limiting the attachment size was one of the easiest ways to avoid having
users overfill their inboxes, which avoided the rather significant cost of
more storage (with redundancy, backup, etc) when they filled them up and
asked for 10+GB mailboxes. Whether it be Exchange or Domino, mailboxes of
that size start to make most systems groan!
