I used DSPAM many years ago, and, have gone back to it again. I am using
dovecot-antispam (well, version 2 for dovecot 2) to do the re-training. Thus
far, I have learned 59 spam, most of which are very similar in nature. My
recollection was that DSPAM learned very quickly, but this is not happening.
Perhaps my memory is bad!
My antispam config looks like this:
plugin {
autocreate = Spam
autosubscribe = Spam
antispam_signature_missing = move
antispam_backend = DSPAM
antispam_signature = X-DSPAM-Signature
antispam_trash_pattern_ignorecase = trash;Deleted *
antispam_spam = Spam
antispam_dspam_binary = /usr/bin/dspam
antispam_dspam_args = --source=error;--signature=%%s
}
My question is this - in the dspam logs, I see (for example) this:
1315501817M<None Specified>11,4e68f61b138342073587969<None Specified>Retrained
Not sure what those nones are. When re-training, does DSPAM really just use the
signature, or does it need the entire message? Should my configuration of
antispam actually be working?
The numbers in dspam_stats DO work, lining up with the log file, i.e., after
moving to the spam folder, I see false negatives rise by 1. My question is more
how can I tell if the actual data is being changed such that it is in fact
learning what spam is? Or, am I just too impatient?
