Hi all,
I got no reply for this issue but in the meantime I solved it:
O DontProbeInterfaces=True
is the setting in sendmail.cf which prevents loopback interfaces to be
scanned (which results in the error issued).

Hi all,
Our sendmail.8.13.1 from the internet express states (sendmail -d0.10 -bv
username) after a IPv6 setup of our Tru64 5.1b server:
... (snipped)
a.k.a.: [IPv6:fe80::616c:7430:0:0]
a.k.a.: [IPv6:2001:4ca0:4101:0:6963:7330::]
a.k.a.: [10.0.0.3]
And in the log it writes a gethostbyaddr error
..sendmail[1667266]: gethostbyaddr(IPv6:2001:4ca0:4101:0:6963:7330::)
failed: 1
..sendmail[1667266]: gethostbyaddr(IPv6:::736c:3000:0:0) failed: 1
A ifconfig alt0 tells me:
alt0: flags=c63<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST,SIMPLEX>
inet x.x.x.x netmask ffffff00 broadcast x.x.x.x ipmtu 1500
inet6 fe80::260:cfff:fe21:45de
inet6 2001:4ca0:4101:0:81:bb:cc:4
which isn't what sendmail thinks the IPv6 address is. We are using 128 bit
IPv6 (no tunneling or 6to4 conversion etc.); DNS is set up properly (also
reverse mapping is o.k.)
What is going on?

Rudi Gabler
