I'm not sure you can express this in absolute terms.  If a message is 
so large delivery of it impedes the ability of you neighbors to use 
the net, it's too large.  But I have no idea how to apply a criteria 
like that in a realistic way.  Once a message has been handed to the 
first smtp-receiver, determining if the path it transits obstructs 
other traffic at any point along its path is well beyond the ken of 
the original sender.

I suppose an smtp sender could apply a size-of-message policy to sort 
it's queue.  That at least would keep a large message from 
obstructing a gaggle of shorter ones, especially for a slow link.

Defining "too large" is tricky.  "Too large for whom?  The sender, 
the receiver or any hop in between?  Eudora will warn a user if he 
queues a message larger than a certain value.  The threshold can be 
set by the user.  The motivation is to warn senders using a dial-up 
connection they are about to spend a long time on the phone.  It 
might encourage senders to have some consideration for receivers of 
their message, although I wouldn't claim much chance of that.
