Stan Ryckman found the following in his backup directory:
| -rw------- 1 stanr 3063 Nov 4 03:31 .nfsA0c724.4
| -rw------- 1 stanr 1780 Nov 3 23:00 .nfsA47da4.4
| -rw------- 1 stanr 849 Nov 3 23:22 .nfsA481f4.4
| -rw------- 1 stanr 2293 Nov 11 11:28 .nfsA737d4.4
Those look like some of the temporary names procmail uses while it is trying
to write a file out, which it renames if things go well. I noticed that they
all came from a 4h 31 span overnight; perhaps there was some systems work
being done on your machine that screwed things up?
I wouldn't just blame procmail. This seems to be an artifact of using an
NFS server to write files. I have seen these left around by all sorts of
programs--often when a file by the "right" name has the same contents.
May I recommend this?

OR (possibly in a cron job):
find <dir> -name ".nfs*" -atime +7 -exec rm -f {} \;
(double check that command, especially the '+' -- I always have trouble with
'find')
