> But no messages got classified spam or unsure, AFAICT. > Even after I move some of the spam training messages into my > inbox, they're not classified as spam. I think I have fixed this now. I've changed imapfilter so that instead of iterating through the entire RFC822 message when we go through a folder, we just retrieve the headers (which we can use to determine if the message has been trained/classified or not). If we then have to do something to the message, the substance is retrieved. This should speed things up (no more retrieving the substance many times), and I think I fixed the bug that stopped messages being filtered along the way. If you could check it (again!) that would be great. If it's still not working, could you run it with "-i4" and see whether it's doing any FETCH RFC822[.PEEK] commands? If not, then there's something up with the db checking, if so then it's something else. BTW, I am working on the headers-with-no-line-endings thing (I grabbed the el source that you suggested), but it's taking a while... =Tony Meyer

> Is there a reference on how to set up the .ini file manually? There's a question about this in FAQ.txt, although you'll have to do a wee bit of Python to get a list of the options that need setting. Basically, though, you'll want this in your ini file: [pop3proxy] servers:pop.example.com:110 ports:110 persistent_storage_file:path/to/database.db (Obviously with the appropriate values replaced). This should be all that you need to use pop3proxy. The FAQ has details for finding out what the other options that you can set are. I will make sure that I figure out the temp file problem, but this might not be until tomorrow. =Tony Meyer

This has a message with the classification header, but no blank line separating the headers and the body. So parsing the headers dies. Any idea why this might happen, Tim? I'll have a look, but I probably won't be able to get to this tomorrow. I *suspect* that it's a problem in message.py rather than imapfilter.py, but I wouldn't guarantee it. =Tony Meyer

Configuration page of pop3proxy fails

Yes it's linux. the data directory is /opt/spam/spambayes/data which was empty. Now it has: -rw-r--r-- 1 root root 0 Apr 29 19:41 bayescustomize.ini -rw-r--r-- 1 root root 12288 Apr 29 19:34 hammie.db drwxr-xr-x 2 root root 4096 Apr 29 19:34 pop3proxy-ham-cache drwxr-xr-x 2 root root 4096 Apr 29 19:34 pop3proxy-spam-cache drwxr-xr-x 2 root root 4096 Apr 29 19:34 pop3proxy-unknown-cache -rw-r--r-- 1 root root 12288 Apr 29 19:34 spambayes.messageinfo.db Note the .ini is empty. Is there a reference on how to set up the .ini file manually? thanks for the help sean _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail

One potential problem with this filter apporach
by John Clegg April 30, 2003

April 30, 2003

Hi I am really impressed with this implementation of a spam filter. Like everyone else I (and my company) have been plagued by spam. I was thinking about the way the spambayes works, and I think I have thought of a way spammers could get around it. A devious spammer could use images as instead of text. So the email would just contain an HTML table. It's something you guys should think about how your filter will operate on these types of emails. FYI: I am former CTO of Baazee.com from India and I have designed email delivery systems for the company. Keep up the good work. Regards John Clegg Tech Consultant

[sean darcy] > "/usr/lib/python2.2/site-packages/spambayes/Options.py", line 1303, > in update_file > shutil.copyfile(out.name, filename) > > File "/usr/lib/python2.2/shutil.py", line 28, in copyfile > fsrc = open(src, 'rb') > > IOError: [Errno 2] No such file or directory: '(fdopen)' What platform is this with? (The /usr/lib suggests some sort of *nix flavour). I'm pretty sure that this is a problem with the temporary file. What it's doing is saving the options to a temporary file ('out'), and it then copies this over to the actual config file. (This means that if something goes wrong halfway, the original is still ok). It seems to me from the trace that the temp files is giving '(fdopen)' as it's filename. The correct filename is retrieved on Windows; I can't test elsewhere. I need the filename to pass to copyfile. Could one of the Python'ly wise people tell me the correct way to do this so I can fix Options.py? =Tony Meyer

I'm just trying out spambayes. I dl'd from cvs. Installed. Then cd'd to /opt/spam/spambayes/data. Then: pop3proxy.py -b Loading database... Done.

Problem installing SpamBayes Outlook Addin
by Dave Hylands April 29, 2003

April 29, 2003

Hi, I'm running Windows 2000 (SP3) with Outlook XP installed. I have Python 2.2.2 installed and win32all-152 installed. When I try to execute the SpamBayes-Outlook-Setup-002.exe program, it gets partway through the installation and then dies with the following error: C:\Program Files\Spambayes Outlook Addin\spambayes_addin.dll Unable to register the DLL/OCX: DllRegisterServer failed; code 0x00000000. Click Retry to try again... Does anybody have any ideas how I might get around this problem? -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/

Spambayes doesn't really care what messages contain, just whether they (well, the tokens) are more similar to messages you have trained as spam, or those you've trained as ham. Unless you have a lot of ham that looks like this, then the few clues that would get generated would probably have high spam prob. There's also the headers, of course, which generate their own clues. I don't think that this method would get around a pseudo-bayesian system (like Spambayes) nearly as well as other methods - like quoting a message that you wrote at the end of their mail. =Tony Meyer
