[Exim] System filter versions

Nigel,

Could you please specify which are the file extensions you added to
system_filter.exim v 0.17? Would it be possible to keep older versions
available on the web site?

And here's a well-deserved cheer to the exim system filter and its
creators. Our company Security Team closed Internet gateway traffic both
inbound and outbound to protect the intranet as well as others while they
organized efforts to recover. The only Internet mail permitted was to
certain addresses which are handled by Exim mail servers which in the words
of the Security Team "will not pass the virus"

thanks,
Reena
