Hm,

we don't want to reject the mails, because we want to spare our
netword avarage of our 64k ISDN-WAN. So our central mailserver
should freeze all mails > 500k and release them in the evening,
when no one works in our WAN.
Is it possible to add this into our system-filter ?

A reject of mails >10000k is also in our system_filter:


if $message_size above 10240K
then
fail text "tooooooooo big!"
endif

But which text than fail text is needed to notify the user
of frozen messages:

if $message_size above 500K
then
freeze "A little bit to big"
... ### and now to message to the sender ### ...
endif
