What's changed relating to localhost then?

I can confirm this behaviour. It is possible to force the local
address to 127.0.0.1 though.

[xi at borg ~]$ telnet 127.0.0.1 25                                        [19:39]
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 borg.borderworlds.dk ESMTP Postfix

Nov 22 19:39:44 borg postfix/smtpd[2683]: connect from borg.borderworlds.dk[10.1.0.2]

[xi at borg ~]$ telnet -s 127.0.0.1 127.0.0.1 25                           [19:40]
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 borg.borderworlds.dk ESMTP Postfix

Nov 22 19:40:06 borg postfix/smtpd[2683]: connect from localhost[127.0.0.1]

Fortunately this behaviour didn't break anything here, but it does seem
broken nonetheless.

I updated my machine earlier today and got 5.2-BETA:

FreeBSD borg.borderworlds.dk 5.2-BETA FreeBSD 5.2-BETA #3: Sat Nov 22 13:25:47 CET 2003     root at borg.borderworlds.dk:/usr/obj/usr/src/sys/BORG  i386
