Good day,
Thank you very much for taking the time to think about this and for your
detailed reply.
Yes, /var/dspam/data was already there after I installed the package (I
am not using -current, just OpenBSD 4.0 from the CD and packages from
mirror.arcticnet.ca. I am not sure whether the way I have set stuff up
is the best possible approach but after I did a chmod 2771 on /var/dspam
I am able to retrain etc. On this test server, every spam message has
been classified correctly!! dspam seems to complement spamd (the OpenBSD
spamd) and milter-regex very well, so far.
In case there is a better way than doing chmod 2771, please do let me
know. Here is the output from ls -laR /var/dspam. The reason
why /var/spam/data/vsankar and /var/dspam/system.log has 2777 is because
I couldn't get the system statistics and quarantine information from the
dspam.cgi program without opening that up.
Also, there is still one final problem. If user vsankar (unprivileged
account) uses the dspam.cgi program and decides to reclassify a message
already classified as spam by dspam, I get the following error
in /var/log/maillog
Dec 17 09:38:37 mx1 dspam[8781]: Delivery agent returned exit code
1: /usr/libexec/mail.local -d vsankar
Dec 17 09:38:38 mx1 mail.local: may only be run by the superuser
For now, I am thinking of avoiding using the dspam.cgi altogether and
just moving the vsankar.mbox quarantine file into /home/vsankar/mail and
accessing it through my webmail client if I ever want to reclassify
email. But it would be nice to be able to do a "Deliver Checked" from
the dspam.cgi interface.

Also, just as an FYI, this is what I get with dspam_stats
vsankar:
TP True Positives: 47
TN True Negatives: 2
FP False Positives: 5
FN False Negatives: 16
SC Spam Corpusfed: 0
NC Nonspam Corpusfed: 0
TL Training Left: 2493
SHR Spam Hit Rate 74.60%
HSR Ham Strike Rate: 71.43%
OCA Overall Accuracy: 70.00%
The 5 false positives were due to me not feeding dspam any notspam
messages. What happened was I forwarded (as root) the "Welcome to
OpenBSD 4.0" message to vsankar five times and they all got classified
as spam. After retraining, I am able to send that message through from
root to vsankar. Since this is a test machine (MX preference 30 compared
to 10 on the real mail servers) I only get spam on this machine, so I
still have some ways to go to understand how this all works in a
real-life scenario.
Thanks again,
Vijay
