Not only that, but something is broken in your MUA that resulted in
the log entries you included that showed the above being cut off and
lost.
As is, your sendmail setup looks right to me. Are you able to telnet
from that machine with those source and destination address?
telnet -b 192.168.2.5 192.168.1.10 25
If that doesn't go through, then the problem is your network level
setup (routing, filtering, etc) and not your sendmail setup at all.
If that telnet does work, well, you _did_ remember to restart sendmail
after changing the sendmail.cf, right?
