short log with dcc

The reason is the waste of resources, servers are quite busy with email 
traffic. 
Writing files to disk is expensive (all stuff is in memory now, no any 
disk i/o),
writing files into memory and frequent postprocessing them with script 
is an alternative,
but it does not look elegant and needs more memory.

I will look, thanks.

I understand that. Did not know about qmail.

I use postfix+dccm, I do not know yet when postfix writes message-id, 
before or after milter.
I do not see any other appropriate keys. Probably, I could create one 
with milter before dccm. Probably, the dcc checksum could be the key itself.

Any advice about code hook place?
