Postfix in file too larg

[Jani]

Zdravo!

Ali mi prosim lahko kdo da kak nasvet, za sledeč problem:
Okolje:
RH 80, Postfix.

namreč Postfix naj bi zavračal priponke, ki so dolge npr. 200K, čeprav,
če pogledam z postconf za velikosti ni videti nobenih težav:

[root at antares root]# postconf | grep mailbox
home_mailbox =
mailbox_command =
mailbox_command_maps =
mailbox_delivery_lock = flock, dotlock
mailbox_size_limit = 51200000
mailbox_transport =
virtual_mailbox_base =
virtual_mailbox_limit = 51200000
virtual_mailbox_lock = fcntl
virtual_mailbox_maps =


pa vendar pošiljatelj dobi nazaj tako sporočilo, konkretno je bila priponka
dolga 280 K.
