So, I finally did the exim4 upgrade that brought tainting and has now
broken my mailman config.
Note that tainting was introduced in one version and
later exended. You might as well ensure your config works
with the latest version.
I understand why tainting and the basics, but in the case of the mailman
transport I wrote 20+ years ago, it is safe and I'd like to untaint
local_part.
Note that require_files encsures that local_part can't be random crap
or the filematch would fail and the transport would never be called.
Still, I tried to untaint with address_data and pass it to transport,
but it's still tainted
Did you try using $local_part_data ?
That is an untainted copy of $local_part that is *usually* available.
Similarly there is $sender_address_data.
