Apparently not; he just got a message from you that had obviously been through
it at your end. The messages I had from you just now had lots of extra ^Ms,
too.

But there's absolutely nowhere that we can see that this should happen.

Could you try setting $\ = ""  in the "WriteHeaderFile" function
in sendmail.pl, like this:

# Write a fake email header file for the given message id.
sub WriteHeaderFile {
  my($OutDir, $id, $RHeaders) = @_;
  my $Header = new FileHandle;

  Lock::openlock($Header, ">$OutDir/$id.header", "w")
    or Log::DieLog("Cannot create + lock headers file $OutDir / $id.header, %s", $!);
# if debugging not desired
#  print $Header @$RHeaders;
# if debugging desired

  $\ = "";

  foreach(@$RHeaders) {
    #Log::DebugLog("Output header ($_)\n");
    print $Header $_;
  }
  print $Header "\n";
  Lock::unlockclose($Header);
}


...and see whether that helps.

If it's the random memory corruption thing, then it'd work with 5.005 - is
it possible to have both perls installed at once? I can't remember.

I think we need to persuade a perl guru that they need to run mailscanner -
perl 5.6 just fails too often. If they need something to expose all their
bugs, this is it.
