I've built a "pythonfilter" application for courier's global filtering mechanism. It's under 200 lines of just python, and interfaces with courierfilter. It should be very resilient to failures, and it's multithreaded. It loads python modules from a user-defined directory and hands each message to each module. If the modules don't reject it, then pythonfilter will approve it. If any module rejects it, pythonfilter immediately passes that failure back to courierfilter. On top of that, I'm going to port portions of the qmail-scanner (whose performance is terrible!) to python, as modules for pythonfilter. Once finished, it will have support for all of the virus scanners supported by qmail-scanner. -- If I had a dollar for every brain that you don't have, I'd have one dollar. - Squidward to SpongeBob ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

As fate would have it just as I started this email, I was pulled in to some mail server issues and noticed that the respawnhi thing had happened again.

It's much too late to do any debugging right now, but I'll be over this tomorrow.

If a module can't modify the original, then I suppose what I'll do is rewrite the message, privately submit a cleaned version of the message into the queue, and reject the original with a message indicating that the message will be cleaned and received by the intended recipient. The other thing I was going to ask you was about the control files. My python filter gets the full path to the message body, but after that it just reads the queue name from the socket, AFAICT.

Here's a small quote from the document at: http://www.ietf.org/internet-drafts/draft-ietf-imapext-thread-07.txt Note that parentheses enclose a unit of a message and all its children. As message numbers progress _within parentheses_ you get a message and its children. Anyway, here's the example. Let me know what you think. Example:S: * THREAD (2)(3 6 (4 23)(44 7 96)) The first thread consists only of message 2. The second thread consists of the messages 3 (parent) and 6 (child), after which it splits into two subthreads; the first of which contains messages 4 (child of 6, sibling of 44) and 23 (child of 4), and the second of which contains messages 44 (child of 6, sibling of 4), 7 (child of 44), and 96 (child of 7). Since some later messages are parents of earlier messages, the messages were probably moved from some other mailbox at different times. -- 2 -- 3 \-- 6 |-- 4 | \-- 23 | \-- 44 \-- 7 \-- 96 Jeff -- Jeff Tucker Williams Consulting, Inc.

Checking the logs I found this message: Dec 6 04:24:21 quattro courierd: SHUTDOWN: respawnhi limit reached. and then for the next couple of hours until I forcefully stopped it and restarted it: Dec 6 04:24:53 quattro courierd: Waiting. shutdown time=none, wakeup time=none, queuedelivering=1, inprogress=1 Searching a bit, I see I had the same problem someone else had: http://www.ultraviolet.org/mail-archives/courier.2001/5628.html The mail server is busy much of the time, but I don't think it's busy enough to naturally hit the respawnhi timeout. It looks like somehow courier missed that a child finished and that's why it hit the respawnhi timeout. The system is Linux 2.2 running Courier 0.35.1.

I don't use this as a virii scanner simply because I forward domain mail to

the attachments.
On a secondary note, I am away until Jan 5 but on my return, I plan on
