Sure, you could pass $&{auth_authen} along in SEnvFromSMTP (and then split
the two values in make_srs, so as to determine whether or not to do SRS
rewriting). Question, of course, is: do you really want to do this? SRS is
meant to give you a usable MFROM envelope, to be used within SPF (or to
stop fake-DSNs). It wasn't meant to not be used when a user is
authenticated. I mean, the two are simply unrelated.
I think the better approach (which I use internally) is to simply parse
the recipient along, and determine via a whitelist, based on the domain
used, whether or not we do SRS for this specific recipient.
