You don't actually need Mail::SRS to do SRS in Exim -- it's doable
purely in routers. http://david.woodhou.se/eximconf/include/routers-ses
has an example, which behaves better than Mail::SRS will because it'll
perform the mangling only when it's actually _necessary_, rather than on
all mail. It's documented at http://www.infradead.org/rpr.html but the
configuration shown there is more complicated because it includes
workarounds for problems with older versions of Exim.

Actually I only really use that for preventing fake bounces to myself; I
don't do SRS for forwarded messages because I haven't added many domains
to my 'spf-afflicted-domains' configuration lookup file. You probably
shouldn't bother with SRS -- SPF is a fundamentally broken concept
anyway. See http://david.woodhou.se/why-not-spf.html
