4.1) Constructing Mail Addresses. General
Unfortunately, the internet mail system is made up of a huge number of nearly incompatible networks. Mail addresses are constructed with various types of punctuation that mean various things .. indeed, some punctuation means one thing in one domain and another in another domain. I have found that the absolute best way to construct a mail address is either with the '@' format or with a '!' path.
If your feed is a 'smart' host, any fully domained mail address can be replied to with simply:
user@fubar.subdomain.subdomain....domain
dillon@apollo.west.oic.com
Any address with dots in it is called a fully domained address. Unfortunately, there are a few exceptions... any address ending with .UUCP is *NOT* I repeat, *NOT* a domained address... it's a hack that some sendmails will add to properly route the mail internally. This hack generally extends to the From: field of an email message, and AmigaUUCP will do this, but not being a domain, you cannot SPECIFY a .UUCP trailer in the To: address. For example, my UUCP address was:
uunet.uu.net!overload
Note that there is NO .UUCP specification tacked on to overload. Note also that when you specify your UUCP address in your signature you should start with a fully domained machine name, *not* one ending with .UUCP.
On other fronts, some unexperienced administrators will give their machines a full domain name without properly registering it. If you have not registered your domain with the proper authorities, DO NOT GIVE YOUR MACHINE A FULL DOMAIN.
For example, when I first connected to my feed, which is uunet, I did not have a .US domain and so my machine name was simply 'overload'. After I registered in the .US domain I changed my machine name to its registered equivalent, 'overload.Berkeley.CA.US'.
