you're getting the dns timeout because you're off-line.  when you're
off-line, sendmail can't look up (or verify) the existence of the
address to which (or from which) you are sending the mail, so it stays
in the client queue.  when you go back on-line, then the dns lookups
can work again, so the queue can be flushed.

this is perfectly normal behavior.

when you were using 8.11.6, the binary was suid root and used one
queue for all mail.

now that you're using 8.12.8, the binary is sgid to the smmsp group,
and uses two queues: one for local collection and one for everything
else (into which the locally collected mail is moved by way of smtp
between the process you ultimately started and the smtp daemon
actually running as root).

so you have two "received:" headers because two sendmail processes
handled the mail.  note that the first one (the bottom-most one in
your sample above) says "8.12.8/8.12.8/Submit" and the other does not.
