This sounds like a setuid() issue with OpenBSD, but for reference, I
have got to this point:
Adding this:
if (getpwuid(real_uid) == NULL)
{
DEBUG(9) debug_printf("getpwuid failed: %s\n", strerror(errno));
}
before the "if (exim_uid_set)" line (src/exim.c:1940 odd) make
everything work, but removing it and putting it after the if block,
then fails again.
Examining the libc routines, and the interaction with YP leads me to
believe that within the getpwent.c file __initdb() is called first
time though, and caches the entry, but if this is not done while root,
the uid/euid combination seems to confuse the YP server, which only
serves the secure passwd map to priveledged users (low ports I guess).
So, this is not a directly exim problem, but it might be worth getting
into the mailing list archives in case a *BSD user sees something
similar.
I will now go and play with libc...
