[Mailman-Users] Help tracing a delivery problem -Qmail-mailman-vmailmgr

Did a bit more playing around.

I've figured out that there are three subroutines to the qmail-to-mailman.py

The first checks for certain addresses and sends it to qmail-inject if
they're present,

The second strips out information from the part of the header that contains
"mailman" (if present), processes it, assigns options variables if they're
applicable and passes them on to the mailman/mail/mailman binary.

If both those two fail, it gets sent to the third (called bounce) which
generates a rejection message and instructions to go to the webpage for

Messages going through the script are failing to be caught by the second
subroutine.  But I've worked around it and rather than letting messages go
to the bounce subroutine, it forces it into the execute mailman binary.

So this mean no e-mail administration is going to be available but at least
it'll work as a listserver.

I'm wondering what the difference is that's causing what I think are valid
messages to skip over the script.

It's a FreeBSD 4.10 server, All but Qmail has been installed from ports.
Python is (perhaps the script might not be friendly with this
version of python?)

If Bruce Perens is still around on this list, I'd love to hear his thoughts
on this.
