The solutions you have out into place seem very reasonable. The people 
you have to deal with don't :(

Most MTA are one size files all. If you want different limits by domain, 
sender, recipient or from and to use for sendmail or postfix (with 
milter support):

These functions are also built into BarricadeMX.
