Okay, I understand. I found another way to trigger the external script by iwatch just touch'ing a file from within mimedefang to a directory which is watched by iwatch. This is quite fast and keeps the script separate from mimedefang. Ciao! Marcus ___ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.

The MIMEDefang working directory gets deleted when the filter finishes. You most likely also want to be a little more careful with the standard file descriptors, so: system("cd / && /usr/local/bin/skript.sh $QueueID < /dev/null > /dev/null 2>&1 &") but more importantly... ask yourself what you need that for and whether it would be better to rewrite skript.sh in Perl and integrated it into your filter directly.

[Mimedefang] calling external shell script without waiting for its end
Hi, happy new year to all! :) When calling an external bash script in filter_end like system("/usr/local/bin/skript.sh $QueueID > /dev/null &"); I get the following error from time to time (mostly on receiving many simultaneously mails): Jan 2 18:38:13 serv mimedefang-multiplexor[7447]: v02HcBAF023342: Slave 1 stderr: shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory Sending the command not into background with an ampersand avoids this error, but I'm looking for something which triggers on an external script and mimedefang should not wait for its finishing.
