What sounds dangerous? Please use proper quoting.

If you meant the sql injection stuff: Just use quote_mysql with every
externally provided string. In your query, it would be $auth1, which is
already quoted in my example for the domain part. Just do the same with
local_part:

... WHERE username='${quote_mysql:${local_part:$1}}' ...

There's no such thing in exim. There's no real need for it, anyway.
