The panic above is actually for `user@example.org`, which is a virtual
domain setup, so `user@example.org` is delivered to `user@localhost`.

As `localhost` is not a directory in `/var/lib/sympa/expl/`, before the
change in `sympa_router` above, the router was actually skipped,
because the line below failed, and the router was skipped.

condition = ${if
eqi{${lookup{status}lsearch{SYMPA_HOME/expl/$domain/$local_part/config}}}{open}{yes}{no}}

With the change for Exim 4.94 to use untainted data

local_parts = dsearch,ret=full;/var/lib/sympa/expl/$domain_data

this line now fails, because `/var/lib/sympa/expl/localhost` does not exist.

Is there a way, to make a failure in this line (non-existing directory)
non-fatal and just skip the router?


Kind regards,

Paul
