Mail that I receive says it's "From: rc". For some reason, even though I can write a small test program to exercise the getlogname() call (or whatever the subroutine is) and verify that it's correct for me, when sendmail runs it, he gets the answer 'rc'! Has anyone else seen a problem like this? Could it have something to do with running setuid root, maybe disassociated from a controlling terminal, and "rc" is the only wtmp entry that seems to fit those conditions?? As always, I'll summarize any Email received.
