Can anyone confirm this behavior on their machine? Doing an
ldd /usr/libexec/sendmail/sendmail shows:
libutil.so.3 => /usr/lib/libutil.so.3 (0x280fd000)
libwrap.so.3 => /usr/lib/libwrap.so.3 (0x28106000)
libssl.so.3 => /usr/lib/libssl.so.3 (0x2810e000)
libcrypto.so.3 => /usr/lib/libcrypto.so.3 (0x2813e000)
libc.so.4 => /usr/lib/libc.so.4 (0x2823e000)
so it's clearly linked with libwrap. What's going on here??
