Summary: real- router in docs should be limited to locally
generated mail
Product: Exim
Version: 4.67
Platform: Other
OS/Version: Linux
Status: NEW
Severity: wishlist
Priority: medium
Component: Documentation
AssignedTo: ph10@hermes.cam.ac.uk
ReportedBy: mh+exim-bugzilla@zugschlus.de
QAContact: exim-dev@exim.org

Hi,

spec.txt contains a real_localuser router in two places which can be used to
bypass local filters. Since spammers can use it to, eh, bypass local filters as
well, it would probably be a good idea to restrict this router to decline for
messages that originated at a remote site.

There is some discussion about this topic in Debian BTS issue #307768, but only
in a side line.

Greetings
Marc
