https://bugs.exim.org/show_bug.cgi?id=2652

Bug ID: 2652
Summary: SRS does not work for postmaster user when forwarded
to gmail
Product: Exim
Version: 4.94
Hardware: x86
OS: Windows
Status: NEW
Severity: bug
Priority: medium
Component: Experimental
Assignee: unallocated@exim.org
Reporter: me@sharktooth.org
CC: exim-dev@exim.org

When using the SRS router, it does not rewrite for postmaster@ and abuse@ email
addresses, but does rewrite for all others. Everything on my domain is
forwarded to a gmail address.

srs_router:
driver = redirect
srs = reverseandforward
data = ${srs_recipient}

I figure there might be something in the SRS side of the code, but I am not
finding anything that is limiting what local users are allowed to use SRS.
