Subject: [exim] Pelase assist with Exim issue
Hello,
I am new to exim and mail server configuration. I completed the install and
setup for exim. I am wondering if I need to have a registered domain in order
to send mail to be delivered externally. I ran some simple tests to see if my
messages were delivered and they say completed, but when I check my inbox no
message. I don't see any errors. Any advice would help, thanks.
It depends...
If you send your emails through a "smarthost", and you pretend to send
emails from a domain that happens to have no protection at all (no SPF,
no DKIM...), then your emails should arrive. Some destination servers
may even accept your emails without having to use a smarthost. However,
this is hardly the route to go! And probably not very honnest, too.
The least you should do is register a free domain name, and probably
setup dynamic DNS. With this setup, and using a smarthost, you should be
fine. I had this setup for years with very few problems. However,
sometimes, I saw some emails rejected because of the free domain name,
which was recognized as such.
Finally, the best thing to do is to have a proper domain name. This is
what I have now, and I hardly ever have any problem, even though my
server runs on a dynamic IP at home. See here:

(the final dot is part of the URL... yes, I know...)
Cheers,
Yves.
