I take it that this is a system filter? If so, you can set
message_filter_user = xxxx
in order to run the filter as a specific user. Otherwise, you could
perhaps make use of some rewriting.

Er, you need to put strings in quotes when they contain spaces.

by "caller", it means the bit of code in Exim that is currently being
invoked. In the case of the constituents of an "if" command in a filter
file, "fail" causes the condition to fail (if I read the code
correctly. :-)
