[Nmh-workers] reason: 554 5.7.0 Message Size Violation

[norm]

This is the first I've ever heard of this rejection reason. The message 
consisted, almost entirely, of an attachment, Spec_05_04_10:04.zip,  a 471,282 
byte zip file.

Is there anything I can do, short of breaking the attachment into several 
pieces, and sending separately?

Is there some way, other than trial and error, to determine the size limit?
