Yuri by default this is set to [127.0.0.1] as denoted by:
http://svn.freebsd.org/base/head/etc/sendmail/freebsd.submit.mc

I believe it has been this way for a very long time. If for some reason 
that you changed the value your self and you would like to revert back to 
defaults you can remove `hostname`.mc & `hostname`.submit.mc and re-run 
make(1) in the /etc/mail directory to give you a default config.

The comment in that file reads:
dnl If you use IPv6 only, change [127.0.0.1] to [IPv6:::1]
