I dont even have any idea what that is!
http://exim.org/exim-html-current/doc/html/filter.html#SECTpipe doesn't
mention this. But fine - I tried googling for a couple of examples, and
found 2 setting 'system_filter_pipe_transport = address_pipe' (eg.
http://www.freesoftwaremagazine.com/articles/exim_and_anti_spam_spamassassin?page=0%2C2).
Looked up 'address_pipe' in the documentation, but still not any the wiser.
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 $address_pipe if
a message is redirected to a pipe due to "aliasing or forwarding"? In which
case, I shouldnt bother, since I'm expecting to run the pipe at the
beginning using system_filter? OTOH, the 2nd link mentions '$address_pipe
contains the text of the pipe command', as if this were not a special case?
These docs have been chasing round in circles.
I've also set system_filter_user, and system_filter_group to the exim user,
to try and see if this helps. It doesnt.
