OK: I agree. Now, let's get back to the real world. Users can use
any client they want, and the overall organization lacks the will
to impose a ban on certain mail clients because the clients' users
insist they need them. Maybe they do too; I am not familiar with
the non-mail components of certain software. It is impossible to
train users effectively with a 5,000:1 ratio of users to user
services staff and steady turnover. So all that's right out.
Blocking attachments by extension saves us about $30,000 worth of
anti-virus software licensing and additional hardware to process
scanning. That sounds good to me.
Banning attachments and HTML mail? That's where this is going.
I think we're going to see it happen.
What would accelerate it would be an alternative way to transmit
files, which is badly needed anyway. Email is the least efficient
way possible, with the encoding that has to be done into bloated
