File name and dlirectory size problems.

Having dccm, dccifd, and dccproc append to existig log files opens
cans of worms.

Yes, but will people who are able to understand what's going on
need more than the current files?

How about making the log file viewer notice that the message was
embargoed and that that the log file is not combined, then on the spot
look for any previous, related log files and combine them into a single

Would the naive combining of log files be a problem?  Could you only
present all of the files of an embargoed message when the user asks
for more information?  Will users care about embargoed spam?
