Hm. DNS lookup would make postmaster startup last much longer, to have 
all addresses resolved. Usually installations will have only some 
well-known non-volatile networks configured, So I'd opt to not use DNS.

I can't remember to have opted for a IPV6 installation, so I believe my 
SuSE 8.1installs IPV6 by default now (and 8.2 too). Then I worked quite 
a while with 7.3 as usual, and was quite surprised about that IPV6 stuff 
when upgrading to 7.4.
This will probably be an issue more and more, when machines get IPV6 
enabled (if by mistake, on purpose or default). The proposed patch will 
handle IPV4 clients as usual.

Andreas
