Hi qmail users,
I have configured a virtual domain for processing the messages through
a filter and then re-send them. I used a classic solution with a
.qmail file:
virtualdomains: debug:debug
.qmail-debug-default: | myfilter | qmail-inject -f "$SENDER" -- "$DEFAULT"
This solution works fine but I have some doubts about the behaviour
when the filter script (myfilter) finishes unexpectedly. If the script
receives a signal (managed or not) that forces it to finish,
qmail-inject will simply understand that the message's body has
finished and will send a incomplete message. The original body will be
lost forever.
I explored a solution catching the signal in the script. The signal
handler sends a new signal (INT) to finish qmail-inject with a proper
error code for showing that the message hasn't been delivered.
Now there is my problem: Which is the proper qmail-inject's pid?
We can't use the group pid because all qmail processes belongs to
qmail-send's group. We can try with parent pid (qmail-inject process
is the myfilter's process parent) but if qmail-inject finishes before
the script, this could send signals to the "init" (the parent
for orphans).
Do you have any signal reliable solution ?
Thanks in advance for your help,
David Jorrin.
PD: Please send me a copy by e-mail. Thanks again.
