From: Seth Randall on 21 Feb 2010 15:19 I am trying to use LUSER_RELAY with preserve_luser_host on Sendmail 8.14.4 my mc file has the following: define(LUSER_RELAY, `relay:exchange.example.com')dnl FEATURE(`preserve_luser_host')dnl mail sent to testemail(a)example.com should forward to exchange.example.com without changing the host, but it keeps failing with the Exchange server returning the message that testemail(a)exchange.example.com could not be reached. Isn't the preserve_luser_host supposed to keep it from rewriting the host name?

Out of curiosity, in what situations does preserve_luser_host actually work? It would seem to me that the use case I have would be the obvious use for it and would therefore work by default. Regardless, I would certainly take a patch for it. Thanks, Seth
