the problem is that sendmail still connects to the remote host always
using default machine IP address.

Not if one uses "DAEMON_OPTIONS( ... Modifier=b ...)"

However, if you have both IPv4 and IPv6 in use, watch out for the bug
- If you're relaying the message (or otherwise redistributing it -
forward, mailing list expansion, etc., ...) and it came in via IPv6
but the destination(s) has(have) no IPv6 addresses, the message gets
stuck and won't be delivered. It would be nice if either a "5.4.4"
class message were generated or a fallback to any IPv4 address that
matches the IPv6-reverse hostname, but neither of those seems to
happen.
