I don't see any mention of "prvs"-anything in there (and, AFAICT from the Exim
spec, BATV == the prvs* expansion items). However your config does talk about
SRS, and (as far as I know) SRS and BATV are two completely separate things.

I actually found that implementing prvs/BATV was fairly straightforward: two
ACL chunks, one redirect router, and a transport option.

Odhiambo: the rewriting / mangling is performed by a "redirect" router, not a
rewrite rule.

I'll happily share the relevant parts of my config, but I don't want to butt
in on David if he was ready to help...
