yes, and even it works with dokumented default config

what does not work is the size=forged-size problem is not implented 
since it only works in postfix eof-data stage in mta, that means we 
would all accept iso file sizes before we discovery that its oversizes 
in the first place

dovecot will tell postfix to reject over quotas based on what is free 
left quotas

it cant be solved better not even in bash

but one thing, it could be changed to use dovecot dict: if this is 
already existing, then postfix could have a policy server that checks 
dict: maps, and basicly this will provide support for dovecot can be 
stopped but postfix still use dict in all supported postconf -m table 
supported, if dovecot support them all

but the current implemention is imho still better
