It doesn't matter for the other hosts, the sender ip address will always 
be the outgoing interface address and not the loopback. It only matters if 
you connect on the local host and have to troubleshoot a connectivity 
issue and confuse something ... Usually, it's rather an advantage because 
in cases where you would just get "localhost" you now get some meaningful 
name. It really depends. However, I have it set this way on all my hosts 
for ten years or more and haven't found a single case where this was a 
problem.
