How to handle „pipe“ is a matter of exim, thus exim needs to know the system_filter_pipe_transport (usually set to „address_pipe“ -- this transport has to exist of course). If you consult the exim spec.txt, you should find several references to system_filter_pipe_transport and to address_pipe. > Here's a compilation of what I've read: > http://exim.org/exim-html-current/doc/html/filter.html#SECTpipe > http://exim.org/exim-html-current/doc/html/spec_html/ch29.html > http://exim.org/exim-html-current/doc/html/spec_html/ch11.html#SECTexpvar > > From the last link, it seems that I should only bother with $address_pipe if > a message is redirected to a pipe due to "aliasing or forwarding"?

Yes, but for system filters, the pipe transport has to be set as well. > I've also set system_filter_user, and system_filter_group to the exim user, > to try and see if this helps. It doesnt. Try exim -bP all | grep system_filter And then try to find the mentioned transport (if any transport is mentioned): exim -bP transport „transport-name“ If this works, we need more ideas ;-) Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann HS12-RIPE ----------------------------------------- gnupg encrypted messages are welcome - key ID: 48D0359B --------------- gnupg fingerprint: 3061 CFBF 2D88 F034 E8D2 7E92 EE4E AC98 48D0 359B -
