What MTA are you using? The server in question returns 554 -- syntax
error, which is a permanent failure code. Your MTA should _not_ drop the
mail, it should bounce it, unless I completely misunderstand SMTP error
codes...
That said, stock qmail-1.03 does _not_ exhibit this behaviour, either.
It does not act on the SMTP SIZE extensions, but neither does it return
any error message -- it simply ignores it. The spamcontrol patch set
against qmail-1.03 apparently implements it fully, but I have not had
the need for it yet....
