I'm trying this question again -- perhaps my original question was too
verbose or too simple or too RTFM?
I have per-domain alias lists, and I'd like to have pipe commands
run the command as a specific user based on the domain name.
The current need for this is so an alias list can contain an address that
runs a command to update the domain's alias file.
I tried adding a "user" setting to the virtual_aliases director but received
D=virtual_aliases T=address_pipe: Child process of address_pipe transport
returned 69 (could mean service or program unavailable) from command:
/etc/exim/update_foo_aliases.pl
