The configuration for our outbound server that used to work under 4.96.2 now has a broken router and I am trying to figure out how to fix it. Any help would be appreciated!

The broken router:

system_aliases:
driver = redirect
allow_fail
allow_defer
data = $local_part@$domain, ${lookup mysql{MYSQL_ALIASES}}
file_transport = address_file
pipe_transport = address_pipe

where MYSQL_ALIASES was initially defined as:

MYSQL_ALIASES = select XXX_GetForwardingAddress('$local_part')

I partially addressed the issues by quoting the local_part in my function call:

MYSQL_ALIASES = select XXX_GetForwardingAddress('${quote_mysql:$local_part }')

Also tried:

MYSQL_ALIASES = select XXX_GetForwardingAddress('${quote_mysql:$local_part_data }')


But this did not fully fix the issue (tainted local_part still taints the SQL function result?):

How do I de-taint / trust the result from my own database here?
