Subject: mailbox size test for appendfile transport
Here's a simple addition to the appendfile transport
driver's private attributes - the attribute is "size",
a long integer object. The newly opened file for
delivery is tested for filesize against the "size"
attribute - if the filesize is > the specification,
the incoming email object is bounced back to sender
with a "mailbox full" message.
This could no doubt be usefully enhanced in a number
of ways, but it's a start...
