Since you're talking about message acceptance, you're wanting
to deal with the main config option message_size_limit.
I am not sure at which point the message_size_limit
comes into play.
The data has only arrived at the point the data acl (or one
of the data-like acls) is run.
In acl_check_rcpt I have several rules regarding those domains.

No, but you don't need to.
or is acl_check_rcpt too late in the configuration for the
message_size_limit-check?
Actually it's too early. But no matter; the option is
documented
as being expanded, meaning that at the time of application
(after data has arrived, so that the amount of data can be
counted)
it can depend on other factors.
meh…
For your purposes, a definition something like
message_size_limit = ${lookup {$domain} partial-lsearch \
{$config_dir/special_domains} {100} {50}}
That does not seem to work. According to the documentation:
$domain: When an address is being directed, routed, or delivered
on its own,
this variable contains the domain. In particular, it is set during
user
filtering, but not during system filtering, since a message may
have many
recipients and the system filter is called just once.
Therefore I guess that $domain is empty when the
message_size_limit is checked.
So it seems I have to accept all the big mails and then reject
them during
routing I guess.
Best,
Niels
