Bug#702358: Please enable SRS

[Richard Stanway]

I'd also like to add my vote to this. Forwarding email is quite a
common use case and SRS is needed in order to be compatible with SPF
and other email reputation techniques.

It took me quite some time to figure out where I should be editing the
Debian package to enable SRS, and then I ran into issues with
dh_shlibdeps not recognising the srs library. It would be great if
this was included by default in the heavy package, since it requires
config options to enable I can't see it hurting any installed
configurations.

There could be an issue with a dependency on libsrs which
unfortunately doesn't seem to have a package yet.
