Package: exim4-config
Version: 4.34-5
Severity: normal
I installed exim4 and exim4-config as an "internet site". I just found that
I could not send mail within my local network, because it refuses to connect
to RFC 1918 hosts. This was difficult to debug, because the error in the
bounce and the log was simply "unroutable address".
I don't see any point to this restriction, and I don't see why exim should
assume that it is on the internet, rather than a private network where these
addresses are perfectly valid. So I would suggest removing this
restriction, or at least making it configurable.
I have my system configured as an "internet site" rather than using a
smarthost because it is a laptop that goes on many networks, and it is
too tedious to reconfigure for every network. But even if this weren't a
problem, I don't think the current exim behavior is the right default.

Upstream issue, easily debuggable with exim -bt.

It does so to avoid delivering e-mail to misconfigured domains to the
wrong place.

Done. Closing the bug. The file holding the restriction is a
dpkg-conffile, feel free to change it with the text editor of your
choice.
I would, however, configure a dedicated router having a list of
domains that are allowed to have a rfc1918 MX, maybe even hard-wiring
the corresponding MX address.

Feel free to remove the restriction completely, and live with

Well, the exim4 maintainers do. Feel free to take the issue to the
technical ctte.
Thanks for your bug report.
