I would just like to now when will there be a version for outlook express coming out base on the same one as outlook uses. Thank for your time and help have a nice day. --- avast!

RE: [Spambayes] why doesn't the pop3 proxy filter all messages?
by The Rolphs Nov. 26, 2004

I can confirm that sending the CAPA causes the session to fail to close reliably from a telnet session through the proxy. Not using the proxy results in correct receipt of mail by the client. Using the proxy results in all mail being received, but many of the messages do not have the X-Spambayes headers. what I think would resolve this is for the proxy to send an extra <CR><LF> after the QUIT command to ensure that the session has closed. I have had two of these cases after changing the check forr SSL setting, but the problem is greatly reduced.

"Check for new version" proxy settings?
by Jerry Williams Nov. 26, 2004

Nov. 26, 2004

The release notes for 1.0.1 talk about putting proxy detail in the configuration file. But I can't find any information on what file and what information needs to be put there in what format. Thanks in advance for any pointers on how to do this.

RE: [Spambayes] email evades Spambayes

I did t his. I can confirm the following: If the CAPA command is given SOME of the time the server connection fails to close after the QUIT command. Under these conditions, the pop3 proxy passes the commands for the next session(s) without filtering the email. It is moderately reproducible. I also have tow cases under 1.0 where this occurred even with very simple pop3 commands sequences, but I have been unable to crisply reproduce this.

> There is a bug of some sort in the pop3 proxy which causes it > to pass all mail without filtering if it hangs. Are you positive? I cannot reproduce this (Eudora, Thunderbird, Outlook Express) - if the proxy hangs, then the mail clients generates an error, as one would expect. Are you certain there isn't a secondary connection directly to the server that's working and gets the mail instead? A test would be whether mail that's downloaded when the proxy hangs has the SpamBayes headers. =Tony.Meyer -- Please always include the list (spambayes(a)python.org) in your replies (reply-all), and please don't send me personal mail about SpamBayes. http://www.massey.ac.nz/~tameyer/writing/reply_all.html explains this.

CAPA should work, although it should strip out PIPELINING and STLS if they are present in the server's response. You should be able to telnet to the proxy and give it a "CAPA" command and get a response. Does that work? > My hypothesis is that if I can get Eudora to not send the > CAPA command, that we should work better. Does this sound > reasonable? If there is a problem with the CAPA command (it's possible, although unlikely, since I can't see how this wouldn't have hit many people already), then it's a SpamBayes problem, so we need to fix something. [Next message] > Ok, when I set never for secure sockets when receiving > options, then the CAPA is not sent and it looks like > things work. I presume you weren't actually using SSL (TLS) in any case, since that wouldn't have worked through the proxy. I still don't understand: (a) Why CAPA is causing problems (b) How mail can be delivered if the proxy dies after a CAPA (is there a second, direct, connection to the mail server?) =Tony.Meyer -- Please always include the list (spambayes(a)python.org) in your replies (reply-all), and please don't send me personal mail about SpamBayes. http://www.massey.ac.nz/~tameyer/writing/reply_all.html explains this.

I can't think of any way that mail could be downloaded through SpamBayes and not get either a X-Spambayes-Classification header or a X-Spambayes-Exception header, or crash. If this happens again, could you switch to running sb_server in verbose mode (put [globals] verbose:True in your bayescustomize.ini file) and see if there's anything unusual in the _pop3proxy.log file that will get created? If it doesn't happen again, it was probably just cosmic alignment or something <wink>. =Tony.Meyer -- Please always include the list (spambayes(a)python.org) in your replies (reply-all), and please don't send me personal mail about SpamBayes. http://www.massey.ac.nz/~tameyer/writing/reply_all.html explains this.

RE: you have a patched pop3 proxy?
by Tony Meyer Nov. 26, 2004

Nov. 26, 2004

> I heard rumors that you have a patched pop3 proxy. > > What fixes have you incorporated? > > How would one get access to it? I don't, really. I have the CVS version of SpamBayes, which will eventually become 1.1 and includes a great many changes, but that's available to anyone that wants to run from source. There are no plans to build a binary version of this until 1.1a1 is ready - I imagine that will be early in the new year. All the changes in the 1.0 branch (i.e. all the bug fixes) that I have are in the (released yesterday) 1.0.1 version. I suspect you're basing this on the message I posted where I offered to make a test version of the installer for someone (who hasn't since responded). That would just have been the same as 1.0.1 but with a tentative change (and maybe extra logging) specifically designed to try and fix one problem. If I was certain that it would if the problem, I'd just make the change, but I'm not. (That particular problem was to do with the Outlook plug-in, IIRC). There's really just two ways to get access to the latest SpamBayes code: * The safe way - wait until a new version is released, and use that. * The bleeding edge way - run from CVS source and risk having things stop working temporarily if things go wrong, or have to rebuild databases (etc) if incompatible changes are made. =Tony.Meyer -- Please always include the list (spambayes(a)python.org) in your replies (reply-all), and please don't send me personal mail about SpamBayes. http://www.massey.ac.nz/~tameyer/writing/reply_all.html explains this.
