Hi,
I'm running a qmail server since a few months now, including bill
shupp's patch (qmail-toaster-patch 0.5), spamassassin 2.55,
qmail-scanner 1.16, vpopmail 5.3.20 and maildrop.
Since 3 days I'm having the following problem:
In the logs qmail-inject shows

@400000003f127c0b14fdf854 starting delivery 237: msg 1097933 to local
kendzorra.de-juergen@kendzorra.de

Unable_to_create_a_dot-lock./

and the mail is resend a hundred thousand times.
I already found some information on qmail-list archives, that
"something in that mix [SA, qmail & vpopmail] is either mangling an
existing Return-Path header, or adding a broken one."
Is there another possible reason for this behaviour, like the sender is
sending a corrupt header, or do I have to search for that in my setup?
If yes, where should I?
Thanks,
Juergen
