Databytes or restrictions for differents domains.

[toomany]

Hi!!

First, I will apologize about my bad english... Sorry.

Well, I know the "weight" restriction for incoming mail by "databytes" file. But isn't fully functional when the same machine has more than one domain with differents necessities.
I read about "qmail-qfilter" and a little perl program, but I don't know:
a) if is it mail::toaster compatible, or
b) if there is another way to obtain de same result.

(The "result" is a different weight mail limitation per domain.)

Anybody could help me, please?

Thank you very much!!
