Can you give a more concrete example?

If the error message is being handed back in SMTP: i.e. something like
550-Failed to expand ${foo}: database down
550 Message is undeliverable

then you need to change your ACL to hide this information: you can set

    message = Unable to route


on the relevant ACL entry, or try

    require  control = no_multiline_response


at the start, which according to the doc does two things:

|  (1)  Extra information that is normally output as part of a rejection       |
|       caused by sender verification failure is omitted. Only the final line  |
|       (typically 'sender verification failed') is sent.                      |
|                                                                              |
|  (2)  If a "message" modifier supplies a multiline response, only the first  |
|       line is output.                                                        |


If you are generating child addresses, and you don't want those child
addresses to be shown, then:

my_transport:
..
hide_child_in_errmsg

Finally, if it's a pipe transport, then turn off "return_output" and
"return_fail_output".

Otherwise, I can only guess at what your problem exactly looks like.
