        Hello!

     First of all, many, MANY THANKS to Brian Candler, who was the 
only man, who noticed my second (!) message about this bug. (The first
was a month ago).

     The sysadmins, whom I advised Exim were shocked, that it sends
internal data in bounce messages. ;-((
     Would you explore idea not to send in bounces _any_ internal 
information? If anyone wants it to be sent, he can add it to 
bounce_message_text manually. (For example, on any internal error
only "Internal error" can be sent.)


     Thank you for patch, but it works only if pass= doesn't contain
space. But really, text of search must not be shown in bounce message
(but should be in log file). (I'll modify it for myself, but it's not 
good.)



         Bye. Alex.
