Summary: host_name tag doesn't allow IP addresses

Initial Comment:
Hello.

I have realised that we cannot put an IP address in 
the 'host_name' tag. Normally, we can send an e-mail 
from a client to a server that doesn't have a domain 
name by just putting it's IP address into square 
brackets like this:
john@[142.56.2.72]
This works, especially if you have put the same IP 
address on the destination server in your /etc/mail/local-
host-names file on one line (for Sendmail):
[142.56.2.72]

Now the problem is that if we specify the IP address 
into square brackets in the 'host_name' tag, then the 
resolved hostname is returned in the e-mail address 
instead of this square brackets IP address.
I have tried several backslashes like '', [], "", %5B and %
5D but nothing does.

Square brackets are still correct to the standard, so I 
think that this is a bug.

Regards,
Daniel
