The panic above is actually for `user@???`, which is a virtual
domain setup, so `user@???` 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
