Solaris is OK.

Hmm.. Or perhaps it should be an transport-option? Like in:
local_delivery:
driver = appendfile;
file = /var/mail/${local_part},
check_free_space = /var/mail:100M
and then hold back (in the spool) all mails to that transport? Then
mails to other transports could continue... A kind of fine-granulated
conditional delivery...
