As long as anything gets sent via unmodified PHP mail() function you are unable
to put anything into the exim command line short of hardcoding it in the php.ini.

This is a known problem with php - in an effort to cut the potential security
hole, mail() supplies one argument to the program ("sendmail") that it spawns -
quoted last parameter (additional_parameters as it is called in the php manual)
thus rendering it unusable (under FreeBSD at least).

Thus exim gets one parameter - '-f add@???' instead of two - '-f', 'add@???'
(this is not to mention the setting in the php.ini, that defaults to 'sendmail -t -i').

Unfortunately nothing short of almost complete rewrite of mail() function implementation
can help this.
