Yep. If that option works as I want than it's exactly what I was
looking for. Thank you. (I tried to find several patterns in google
and specs, but w/o success....)

But --

even with no_smtp_return_error_details I see bounce messages like
(recipient of the original message is not local, we just have to
forward the mail to some other host)

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:


      xxxxxxx@???
        SMTP error from remote mail server after RCPT TO:<xxx@???>:
        host xxxxxxxx.xxx.xxxxxxxxx.xx [xxx.xx.x.xx]:
        550-Verification failed for <meine_bank@???>
        550-Previous (cached) callout verification failure
        550 sender address <meine_bank@???> can't be verifed


but on the other hand (local recipient of the original message (error
was triggered due to NUL chars on LMTP transfer to cyrus)

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:


      xx@???
        (generated from xxxx@???)





While writing this: So does exim differentiate here between local
delivery errors (no details to sender) and remote delivery errors
(details to sender)?
