FreeBSD does support single-user mode. Just type "-s" at the Boot:
prompt. However, I guess single-user mode is not what you'd like.
Sendmail hangs probably due to DNS problems. Try pressing ^C when it
hangs. Depending on how you use the system you should either:
1. Not start sendmail at all (if that's the only problem).
2. Configure name resolution so that everything you need is
self-contained.
3. Press ^C when you boot without the Net.
4. Let the DNS query (if that's indeed what's stopping you) time out.
Note: DNS can take a long time to timeout!
