I've been using DSPAM on incoming mail (after Stevan helping me to get
it going), and I can see by the stats it is definately training. Its
been about 3 days or so, and here are my stats thus far :
dspam:
TP True Positives: 1073
TN True Negatives: 2153
FP False Positives: 3
FN False Negatives: 1275
SC Spam Corpusfed: 25
NC Nonspam Corpusfed: 0
TL Training Left: 344
SHR Spam Hit Rate 45.70%
HSR Ham Strike Rate: 0.14%
PPV Positive predictive value: 99.72%
OCA Overall Accuracy: 71.63%
I can see where it is beginning to catch spam, but my users are also
complaining about all the spam they are receiving.
What do you mean with 'all the spam they are receiving'? They complain
that they receive spam? They complain that they receive false
positive/negative? What do you mean?
One user is reporting spam in 'waves', sometimes it is 4 or 5 ever 15
minutes, sometimes it is 50+ every 15 minutes. He's complained
sometimes there are even several hundred to process at a time (move
to DSPAM/Spam folder). People are just wondering when it'll get the
'kinks' worked out.
Another user reports they've gotten one particular email about
getting a loan 100s of times in the past few days. They keep marking
it spam, but it keeps coming in.
False positives are generally pretty low, but the amount of spam
making it to the inbox is considerably more than what they are used
to (coming off of Google Apps).
I am using TOE mode,
which I know is good, but how long (typically) should it take to get
that overall accuracy up into an efficient level?
If you want fast to get on a efficient level then you should strongly
consider to use a global merged group. If you take the time to read the
mail conversation from the last two or three weeks then you will find
detailed instructions how to setup that.
By a 'global merged' group, are you talking about a group that gets
saved under /var/spool/dspam/group (dspam:shared:* for example)?
I've been trying to use just one global (on my server anyway) group.
Yes. Something like that. So you use a shared group? Is this possible?
dspam:shared:*
Yes, I am using a shared group. All mail gets classified under 1 user.
Is this what you meant by a 'global' group, or is there somehow some
way to share dpsam with other servers?
Thanks for the reply. I didn't see it come in. Actually found your
message in the spam box, no real idea why...
Thanks,
Tim
