That is true but one of the things I do like with the solution I came up with for the place I work is that the spamchecking is done at SMTP-time and if it is judged to be spam it gets rejected there; no collateral spam via bounces etc. Erik.

If he wants to put his neck on the line then I think we should let him. :-) If clhp is too much of a strain on the server I'll take it down and perhaps months down the line when he's come up with a better way I'll let him try it out again. We're here to help CL developers and I think we should try our best to do exactly that. Now, you're right that we shouldn't bend-over backwards for everyone and their needs but this one seems fairly harmless. If the server halts because of a full disk or CPU grinding then that's what happens and I'll be very reluctant to try out clhp again. Anthony feels pretty secure that this won't happen so I'm willing to chance it. That said, this is not really a dictatorship so if the two of you want to outvote me, you can. :-) > Like Mario pointed out, this is why chrooting is *vital*.

And I'd add "running > as nobody" and "cmhod -R o-w" to the list. ;) Anthony, what they are pointing out are likely to be requirements in a production scenario, anyway. Is there a way to make sure that clhp pages do not have access to files outside it's directory structure? Erik.

Ok, looks fairly straightforward. Any risk of this eating up all CPU or something like that? Erik.

[clo-devel] Getting clhp installed on Apache

I don't know if I should direct this here or to admin, but it seems most of you read both lists. Anyway, when I first got CLHP started, I asked if you guys would be willing to install it on the common-lisp.net server. I didn't want to install it until the Apache module was working, and that time has come. So I'd like to know if we can install it, so I can actually use it for the clhp home page? -- (incf *yankees-world-series-losses*)

Look at Franz' FTP server (opensource.franz.com) which is most definitely a package but hardly a library. Much better would it have been if Franz wrote an FTP server library and then wrote their FTP server on top of it. Then, if I thought they approach on the FTP server was poor and wanted to do it differently I wouldn't have to implement the library all over again. In Lisp the technical difference between application and library is certainly less clear than in (for example) C but the programmer still have to think about how others will his software for it to become a good library. > Well now you've given me incentive.

We use Exim at the moment and /etc/aliases to shovel mail into Mailman. I think Exim has some features to redirect messages into your software and then back out again. Erik.

The biggest problem I have here is that I get false positives when I set the this-is-spam score lower than four and most spam I get is between three and four. Erik.
