[exim] Possible bug in Exim

I'll do bugzilla if I'm not crazy but thought I'd post it here first to
see if I'm nuts.


In the transports this works:

helo_data = SERVER_NAME.junkemailfilter.com

However this does not work:

helo_data = $acl_c_helo_data

The helo becomes an empty string. And I'm sure the variable is set
properly. It's as if acl variables don't work in the transport?
