As I have a site with 20.000 members I want to send them a newsletter
from time to time. I have set up my own SMTP server on my computer
with Mac OS X 10.4
The problem now is that I was reading that mail with "localhost" in
the header is recognized as SPAM by many ISP's.
Is there a way to change "localhost" to i.e. the domain name of my
site or my static IP address?
