Hi Philip,
please find attached a quick patch which adds a new log option "working_directory".
This would print out the current working directory to the Log.
In combination with logging arguments, this shows extremly handy, if exim is running on a virtual webserver box, and you are trying to find out which site has a buggy mailform, which is used to send out spam.
I eventually just copied your code, probably not exactly knowing what I am doing...
Currently it will still print out a line for (nearly) every call to exim,
although this should obviously only be printed if exim is called for a locally generated
message.
I tried to use "sender_local", but it wouldn't work as expected - but I'm sure you'd know how to?!
I'd be happy to see this in future releases of exim.
keep up the great work!
best
Philipp
